The Shibboleth Consortium reports:

SAML messages, assertions, and metadata all commonly contain date/time information in a standard XML format.

Invalid formatted data in such fields cause an exception of a type that was not handled properly in the V3 software and causes a crash (usually to the shibd daemon process, but possibly to Apache in rare cases). Note that the crash occurs prior to evaluation of a message's authenticity, so can be exploited by an untrusted attacker.

The problem is believed to be specific to the V3 software and would not cause a crash in the older, now unsupported, V2 software.

Apache CouchDB PMC reports:

Database Administrator could achieve privilege escalation to the account that CouchDB runs under, by abusing insufficient validation in the HTTP API, escaping security controls implemented in previous releases.

Bro Network security Monitor reports:

Bro 2.6.1 updates the embedded SQLite to version 3.26.0 to address the "Magellan" remote code execution vulnerability. The stock Bro configuration/scripts don't use SQLite by default, but custom user scripts/packages may.

Problem Description:

Due to insufficient validation of network-provided data it may be possible for a malicious attacker to craft a bootp packet which could cause a stack buffer overflow.

Impact:

It is possible that the buffer overflow could lead to a Denial of Service or remote code execution.

wordpress developers reports:

WordPress versions 5.0 and earlier are affected by the following bugs, which are fixed in version 5.0.1. Updated versions of WordPress 4.9 and older releases are also available, for users who have not yet updated to 5.0.

Karim El Ouerghemmi discovered that authors could alter meta data to delete files that they weren’t authorized to.

Simon Scannell of RIPS Technologies discovered that authors could create posts of unauthorized post types with specially crafted input.

Sam Thomas discovered that contributors could craft meta data in a way that resulted in PHP object injection.

Tim Coen discovered that contributors could edit new comments from higher-privileged users, potentially leading to a cross-site scripting vulnerability.

Tim Coen also discovered that specially crafted URL inputs could lead to a cross-site scripting vulnerability in some circumstances. WordPress itself was not affected, but plugins could be in some situations.

Team Yoast discovered that the user activation screen could be indexed by search engines in some uncommon configurations, leading to exposure of email addresses, and in some rare cases, default generated passwords.

Tim Coen and Slavco discovered that authors on Apache-hosted sites could upload specifically crafted files that bypass MIME verification, leading to a cross-site scripting vulnerability.

Janos Follath reports:

An attacker who can run code on the same machine that is performing an RSA decryption can potentially recover the plaintext through a Bleichenbacher-like oracle.

Typo3 core team reports:

CKEditor 4.11 fixes an XSS vulnerability in the HTML parser reported by maxarr. The vulnerability stemmed from the fact that it was possible to execute XSS inside the CKEditor source area after persuading the victim to: (i) switch CKEditor to source mode, then (ii) paste a specially crafted HTML code, prepared by the attacker, into the opened CKEditor source area, and (iii) switch back to WYSIWYG mode. Although this is an unlikely scenario, we recommend to upgrade to the latest editor version.

Failing to properly encode user input, online media asset rendering (*.youtube and *.vimeo files) is vulnerable to cross-site scripting. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.

Failing to properly encode user input, notifications shown in modal windows in the TYPO3 backend are vulnerable to cross-site scripting. A valid backend user account is needed in order to exploit this vulnerability.

Failing to properly encode user input, login status display is vulnerable to cross-site scripting in the website frontend. A valid user account is needed in order to exploit this vulnerability - either a backend user or a frontend user having the possibility to modify their user profile.

Template patterns that are affected are:

• ###FEUSER_[fieldName]### using system extension felogin
• <!--###USERNAME###--> for regular frontend rendering (pattern can be defined individually using TypoScript setting config.USERNAME_substToken)

It has been discovered that cookies created in the Install Tool are not hardened to be submitted only via HTTP. In combination with other vulnerabilities such as cross-site scripting it can lead to hijacking an active and valid session in the Install Tool.

The Install Tool exposes the current TYPO3 version number to non-authenticated users.

Online Media Asset Handling (*.youtube and *.vimeo files) in the TYPO3 backend is vulnerable to denial of service. Putting large files with according file extensions results in high consumption of system resources. This can lead to exceeding limits of the current PHP process which results in a dysfunctional backend component. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.

TYPO3’s built-in record registration functionality (aka “basic shopping cart”) using recs URL parameters is vulnerable to denial of service. Failing to properly ensure that anonymous user sessions are valid, attackers can use this vulnerability in order to create an arbitrary amount of individual session-data records in the database.

Gitlab reports:

Arbitrary File read in GitLab project import with Git LFS

The phpMyAdmin development team reports:

Summary

Local file inclusion through transformation feature

Description

A flaw has been found where an attacker can exploit phpMyAdmin to leak the contents of a local file. The attacker must have access to the phpMyAdmin Configuration Storage tables, although these can easily be created in any database to which the attacker has access. An attacker must have valid credentials to log in to phpMyAdmin; this vulnerability does not allow an attacker to circumvent the login system.

Severity

We consider this vulnerability to be severe.

Summary

XSRF/CSRF vulnerability in phpMyAdmin

Description

By deceiving a user to click on a crafted URL, it is possible to perform harmful SQL operations such as renaming databases, creating new tables/routines, deleting designer pages, adding/deleting users, updating user passwords, killing SQL processes, etc.

Severity

We consider this vulnerability to be of moderate severity.

Summary

XSS vulnerability in navigation tree

Description

A Cross-Site Scripting vulnerability was found in the navigation tree, where an attacker can deliver a payload to a user through a specially-crafted database/table name.

Severity

We consider this attack to be of moderate severity.

Mitigation factor

The stored XSS vulnerabilities can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required forms.

A remote attacker could cause the NFS server to crash, resulting in a denial of service, or possibly execute arbitrary code on the server.

Node.js reports:

Updates are now available for all active Node.js release lines. These include fixes for the vulnerabilities identified in the initial announcement. They also include upgrades of Node.js 6 and 8 to OpenSSL 1.0.2q, and upgrades of Node.js 10 and 11 to OpenSSL 1.1.0j.

We recommend that all Node.js users upgrade to a version listed below as soon as possible.

Debugger port 5858 listens on any interface by default (CVE-2018-12120)

All versions of Node.js 6 are vulnerable and the severity is HIGH. When the debugger is enabled with node --debug or node debug, it listens to port 5858 on all interfaces by default. This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost. It has always been possible to start the debugger on a specific interface, such as node --debug=localhost. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable.

Denial of Service with large HTTP headers (CVE-2018-12121)

All versions of 6 and later are vulnerable and the severity is HIGH. By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.

The total size of HTTP headers received by Node.js now must not exceed 8192 bytes.

"Slowloris" HTTP Denial of Service (CVE-2018-12122)

All versions of Node.js 6 and later are vulnerable and the severity is LOW. An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time. Attack potential is mitigated by the use of a load balancer or other proxy layer.

A timeout of 40 seconds now applies to servers receiving HTTP headers. This value can be adjusted with server.headersTimeout. Where headers are not completely received within this period, the socket is destroyed on the next received chunk. In conjunction with server.setTimeout(), this aids in protecting against excessive resource retention and possible Denial of Service.

Hostname spoofing in URL parser for javascript protocol (CVE-2018-12123)

All versions of Node.js 6 and later are vulnerable and the severity is LOW. If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.

HTTP request splitting (CVE-2018-12116)

Node.js 6 and 8 are vulnerable and the severity is MEDIUM. If Node.js can be convinced to use unsanitized user-provided Unicode data for the path option of an HTTP request, then data can be provided which will trigger a second, unexpected, and user-defined HTTP request to made to the same server.

OpenSSL Timing vulnerability in ECDSA signature generation (CVE-2018-0735)

The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key.

OpenSSL Timing vulnerability in DSA signature generation (CVE-2018-0734)

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key.

OpenSSL Microarchitecture timing vulnerability in ECC scalar multiplication (CVE-2018-5407)

OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side-channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key.

powerdns Team reports:

CVE-2018-16855: An issue has been found in PowerDNS Recursor where a remote attacker sending a DNS query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache lookup, possibly leading to a crash. When the PowerDNS Recursor is run inside a supervisor like supervisord or systemd, a crash will lead to an automatic restart, limiting the impact to a somewhat degraded service.

Albert Astals Cid reports:

messagelib is the library used by KMail to display emails.

messagelib by default displays emails as plain text, but gives the user an option to "Prefer HTML to plain text" in the settings and if that option is not enabled there is way to enable HTML display when an email contains HTML.

Some HTML emails can trick messagelib into opening a new browser window when displaying said email as HTML.

This happens even if the option to allow the HTML emails to access remote servers is disabled in KMail settings.

This means that the owners of the servers referred in the email can see in their access logs your IP address.

FasterXML jackson-databind before 2.8.11.1 and 2.9.x before 2.9.5 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath.

When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

The samba project reports:

All versions of Samba from 4.0.0 onwards are vulnerable to infinite query recursion caused by CNAME loops. Any dns record can be added via ldap by an unprivileged user using the ldbadd tool, so this is a security issue.

When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ.

During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process.

During the processing of an DNS zone in the DNS management DCE/RPC server, the internal DNS server or the Samba DLZ plugin for BIND9, if the DSPROPERTY_ZONE_MASTER_SERVERS property or DSPROPERTY_ZONE_SCAVENGING_SERVERS property is set, the server will follow a NULL pointer and terminate

A user in a Samba AD domain can crash the KDC when Samba is built in the non-default MIT Kerberos configuration.

AD DC Configurations watching for bad passwords (to restrict brute forcing of passwords) in a window of more than 3 minutes may not watch for bad passwords at all.

PowerDNS Team reports:

CVE-2018-10851: An issue has been found in PowerDNS Authoritative Server allowing an authorized user to cause a memory leak by inserting a specially crafted record in a zone under their control, then sending a DNS query for that record. The issue is due to the fact that some memory is allocated before the parsing and is not always properly released if the record is malformed. When the PowerDNS Authoritative Server is run inside the guardian (--guardian), or inside a supervisor like supervisord or systemd, an out-of-memory crash will lead to an automatic restart, limiting the impact to a somewhat degraded service.

CVE-2018-14626: An issue has been found in PowerDNS Authoritative Server allowing a remote user to craft a DNS query that will cause an answer without DNSSEC records to be inserted into the packet cache and be returned to clients asking for DNSSEC records, thus hiding the presence of DNSSEC signatures for a specific qname and qtype. For a DNSSEC-signed domain, this means that DNSSEC validating clients will consider the answer to be bogus until it expires from the packet cache, leading to a denial of service.

CVE-2018-14644: An issue has been found in PowerDNS Recursor where a remote attacker sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries from clients requesting DNSSEC validation will be answered with a ServFail.

Albert Astals Cid reports:

Various KDE applications share a plugin system to create thumbnails of various file types for displaying in file managers, file dialogs, etc. kio-extras contains a thumbnailer plugin for HTML files.

The HTML thumbnailer was incorrectly accessing some content of remote URLs listed in HTML files. This meant that the owners of the servers referred in HTML files in your system could have seen in their access logs your IP address every time the thumbnailer tried to create the thumbnail.

The HTML thumbnailer has been removed in upcoming KDE Applications 18.12.0 because it was actually not creating thumbnails for files at all.

NVD reports:

An issue was discovered in GNU patch through 2.7.6. There is a segmentation fault, associated with a NULL pointer dereference, leading to a denial of service in the intuit_diff_type function in pch.c, aka a "mangled rename" issue.

A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6.

GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time.

The PostgreSQL project reports:

CVE-2018-16850: SQL injection in pg_upgrade and pg_dump, via CREATE TRIGGER ... REFERENCING.

Using a purpose-crafted trigger definition, an attacker can run arbitrary SQL statements with superuser privileges when a superuser runs pg_upgrade on the database or during a pg_dump dump/restore cycle. This attack requires a CREATE privilege on some non-temporary schema or a TRIGGER privilege on a table. This is exploitable in the default PostgreSQL configuration, where all users have CREATE privilege on public schema.

NGINX Team reports:

Two security issues were identified in nginx HTTP/2 implementation, which might cause excessive memory consumption (CVE-2018-16843) and CPU usage (CVE-2018-16844).

The issues affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the "http2" option of the "listen" directive is used in a configuration file.

A security issue was identified in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory isclosure by using a specially crafted mp4 file (CVE-2018-16845).

The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the "mp4" directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.

curl security problems:

CVE-2018-16839: SASL password overflow via integer overflow

libcurl contains a buffer overrun in the SASL authentication code.

The internal function Curl_auth_create_plain_message fails to correctly verify that the passed in lengths for name and password aren't too long, then calculates a buffer size to allocate.

On systems with a 32 bit size_t, the math to calculate the buffer size triggers an integer overflow when the user name length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow.

This bug is very similar to CVE-2017-14618.

It affects curl 7.33.0 to 7.61.1.

CVE-2018-16840: use-after-free in handle close

libcurl contains a heap use-after-free flaw in code related to closing an easy handle.

When closing and cleaning up an "easy" handle in the Curl_close() function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.

It affects curl 7.59.0 to 7.61.1.

CVE-2018-16842: warning message out-of-buffer read

curl contains a heap out of buffer read vulnerability.

The command line tool has a generic function for displaying warning and informational messages to stderr for various situations. For example if an unknown command line argument is used, or passed to it in a "config" file.

This display function formats the output to wrap at 80 columns. The wrap logic is however flawed, so if a single word in the message is itself longer than 80 bytes the buffer arithmetic calculates the remainder wrong and will end up reading behind the end of the buffer. This could lead to information disclosure or crash.

This vulnerability could lead to a security issue if used in this or similar situations:

1. a server somewhere uses the curl command line to run something

2. if it fails, it shows stderr to the user

3. the server takes user input for parts of its command line input

4. user provides something overly long that triggers this crash

5. the stderr output may now contain user memory contents that wasn't meant to be available

It affects curl 7.14.1 to 7.61.1.

CVE-2018-16395: OpenSSL::X509::Name equality check does not work correctly

An instance of OpenSSL::X509::Name contains entities such as CN, C and so on. Some two instances of OpenSSL::X509::Name are equal only when all entities are exactly equal. However, there is a bug that the equality check is not correct if the value of an entity of the argument (right-hand side) starts with the value of the receiver (left-hand side). So, if a malicious X.509 certificate is passed to compare with an existing certificate, there is a possibility to be judged incorrectly that they are equal.

CVE-2018-16396: Tainted flags are not propagated in Array#pack and String#unpack with some directives

Array#pack method converts the receiver's contents into a string with specified format. If the receiver contains some tainted objects, the returned string also should be tainted. String#unpack method which converts the receiver into an array also should propagate its tainted flag to the objects contained in the returned array. But, with B, b, H and h directives, the tainted flags are not propagated. So, if a script processes unreliable inputs by Array#pack and/or String#unpack with these directives and checks the reliability with tainted flags, the check might be wrong.

Bitcoin Core reports:

CVE-2018-17144, a fix for which was released on September 18th in Bitcoin Core versions 0.16.3 and 0.17.0rc4, includes both a Denial of Service component and a critical inflation vulnerability. It was originally reported to several developers working on Bitcoin Core, as well as projects supporting other cryptocurrencies, including ABC and Unlimited on September 17th as a Denial of Service bug only, however we quickly determined that the issue was also an inflation vulnerability with the same root cause and fix.

the Apache Spamassassin project reports:

In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed.

Because of this, we are missing the "text" event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service.

Fix a reliance on "." in @INC in one configuration script. Whether this can be exploited in any way is uncertain.

CVE-2018-14618: NTLM password overflow via integer overflow

The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap.

The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow.

This bug is almost identical to CVE-2017-8816.

Corelight reports:

Bro 2.5.5 primarily addresses security issues:

• Fix array bounds checking in BinPAC: for arrays that are fields within a record, the bounds check was based on a pointer to the start of the record rather than the start of the array field, potentially resulting in a buffer over-read.
• Fix SMTP command string comparisons: the number of bytes compared was based on the user-supplied string length and can lead to incorrect matches. e.g. giving a command of "X" incorrectly matched "X-ANONYMOUSTLS" (and an empty commands match anything).

Address potential vectors for Denial of Service:

• "Weird" events are now generally suppressed/sampled by default according to some tunable parameters.
• Improved handling of empty lines in several text protocol analyzers that can cause performance issues when seen in long sequences.
• Add `smtp_excessive_pending_cmds' weird which serves as a notification for when the "pending command" queue has reached an upper limit and been cleared to prevent one from attempting to slowly exhaust memory.

Node.js reports:

OpenSSL: Client DoS due to large DH parameter

This fixes a potential denial of service (DoS) attack against client connections by a malicious server. During a TLS communication handshake, where both client and server agree to use a cipher-suite using DH or DHE (Diffie-Hellman, in both ephemeral and non-ephemeral modes), a malicious server can send a very large prime value to the client. Because this has been unbounded in OpenSSL, the client can be forced to spend an unreasonably long period of time to generate a key, potentially causing a denial of service.

OpenSSL: ECDSA key extraction via local side-channel

Attackers with access to observe cache-timing may be able to extract DSA or ECDSA private keys by causing the victim to create several signatures and watching responses. This flaw does not have a CVE due to OpenSSL policy to not assign itself CVEs for local-only vulnerabilities that are more academic than practical. This vulnerability was discovered by Keegan Ryan at NCC Group and impacts many cryptographic libraries including OpenSSL.

Unintentional exposure of uninitialized memory

Only Node.js 10 is impacted by this flaw.

Node.js TSC member Nikita Skovoroda discovered an argument processing flaw that causes Buffer.alloc() to return uninitialized memory. This method is intended to be safe and only return initialized, or cleared, memory. The third argument specifying encoding can be passed as a number, this is misinterpreted by Buffer's internal "fill" method as the start to a fill operation. This flaw may be abused where Buffer.alloc() arguments are derived from user input to return uncleared memory blocks that may contain sensitive information.

Out of bounds (OOB) write

Node.js TSC member Nikita Skovoroda discovered an OOB write in Buffer that can be used to write to memory outside of a Buffer's memory space. This can corrupt unrelated Buffer objects or cause the Node.js process to crash.

When used with UCS-2 encoding (recognized by Node.js under the names 'ucs2', 'ucs-2', 'utf16le' and 'utf-16le'), Buffer#write() can be abused to write outside of the bounds of a single Buffer. Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written.

Problem Description:

When using WPA2, EAPOL-Key frames with the Encrypted flag and without the MIC flag set, the data field was decrypted first without verifying the MIC. When the dta field was encrypted using RC4, for example, when negotiating TKIP as a pairwise cipher, the unauthenticated but decrypted data was subsequently processed. This opened wpa_supplicant(8) to abuse by decryption and recovery of sensitive information contained in EAPOL-Key messages.

See https://w1.fi/security/2018-1/unauthenticated-eapol-key-decryption.txt for a detailed description of the bug.

Impact:

All users of the WPA2 TKIP pairwise cipher are vulnerable to information, for example, the group key.

Problem Description:

A researcher has notified us of a DoS attack applicable to another operating system. While FreeBSD may not be vulnerable to that exact attack, we have identified several places where inadequate DoS protection could allow an attacker to consume system resources.

It is not necessary that the attacker be able to establish two-way communication to carry out these attacks. These attacks impact both IPv4 and IPv6 fragment reassembly.

Impact:

In the worst case, an attacker could send a stream of crafted fragments with a low packet rate which would consume a substantial amount of CPU.

Other attack vectors allow an attacker to send a stream of crafted fragments which could consume a large amount of CPU or all available mbuf clusters on the system.

These attacks could temporarily render a system unreachable through network interfaces or temporarily render a system unresponsive. The effects of the attack should clear within 60 seconds after the attack stops.

Problem Description:

On certain Intel 64-bit x86 systems there is a period of time during terminal fault handling where the CPU may use speculative execution to try to load data. The CPU may speculatively access the level 1 data cache (L1D). Data which would otherwise be protected may then be determined by using side channel methods.

This issue affects bhyve on FreeBSD/amd64 systems.

Impact:

An attacker executing user code, or kernel code inside of a virtual machine, may be able to read secret data from the kernel or from another virtual machine.

The phpMyAdmin development team reports:

Description

A Cross-Site Scripting vulnerability was found in the file import feature, where an attacker can deliver a payload to a user through importing a specially-crafted file.

Severity

We consider this attack to be of moderate severity.

The freedesktop.org project reports:

The functions XGetFontPath, XListExtensions, and XListFonts are vulnerable to an off-by-one override on malicious server responses. The server replies consist of chunks consisting of a length byte followed by actual string, which is not NUL-terminated. While parsing the response, the length byte is overridden with '\0', thus the memory area can be used as storage of C strings later on. To be able to NUL-terminate the last string, the buffer is reserved with an additional byte of space. For a boundary check, the variable chend (end of ch) was introduced, pointing at the end of the buffer which ch initially points to. Unfortunately there is a difference in handling "the end of ch". While chend points at the first byte that must not be written to, the for-loop uses chend as the last byte that can be written to. Therefore, an off-by-one can occur.

The length value is interpreted as signed char on many systems (depending on default signedness of char), which can lead to an out of boundary write up to 128 bytes in front of the allocated storage, but limited to NUL byte(s).

If the server sends a reply in which even the first string would overflow the transmitted bytes, list[0] (or flist[0]) will be set to NULL and a count of 0 is returned. If the resulting list is freed with XFreeExtensionList or XFreeFontPath later on, the first Xfree call is turned into Xfree (NULL-1) which will most likely trigger a segmentation fault. Casting the length value to unsigned char fixes the problem and allows string values with up to 255 characters.

Database Administrator could achieve privilege escalation to the account that CouchDB runs under, by abusing insufficient validation in the HTTP API, escaping security controls implemented in previous releases.

The PostgreSQL project reports:

CVE-2018-10915: Certain host connection parameters defeat client-side security defenses

libpq, the client connection API for PostgreSQL that is also used by other connection libraries, had an internal issue where it did not reset all of its connection state variables when attempting to reconnect. In particular, the state variable that determined whether or not a password is needed for a connection would not be reset, which could allow users of features requiring libpq, such as the "dblink" or "postgres_fdw" extensions, to login to servers they should not be able to access.

CVE-2018-10925: Memory disclosure and missing authorization in `INSERT ... ON CONFLICT DO UPDATE`

An attacker able to issue CREATE TABLE can read arbitrary bytes of server memory using an upsert (`INSERT ... ON CONFLICT DO UPDATE`) query. By default, any user can exploit that. A user that has specific INSERT privileges and an UPDATE privilege on at least one column in a given table can also update other columns using a view and an upsert query.

Oracle reports:

Multiple vulnerabilities have been disclosed by Oracle without further detail. CVSS scores 7.1 - 2.7

The shibboleth project reports:

SAML messages, assertions, and metadata all commonly make use of the XML Signature KeyInfo construct, which expresses information about keys and certificates used in signing or encrypting XML.

The Apache Santuario XML Security for C++ library contained code paths at risk of dereferencing null pointers when processing various kinds of malformed KeyInfo hints typically found in signed or encrypted XML. The usual effect is a crash, and in the case of the Shibboleth SP software, a crash in the shibd daemon, which prevents access to protected resources until the daemon is restarted.

Problem Description:

One of the data structures that holds TCP segments uses an inefficient algorithm to reassemble the data. This causes the CPU time spent on segment processing to grow linearly with the number of segments in the reassembly queue.

Impact:

An attacker who has the ability to send TCP traffic to a victim system can degrade the victim system's network performance and/or consume excessive CPU by exploiting the inefficiency of TCP reassembly handling, with relatively small bandwidth cost.

Mitre reports:

ZNC before 1.7.1-rc1 does not properly validate untrusted lines coming from the network, allowing a non-admin user to escalate his privilege and inject rogue values into znc.conf.

ZNC before 1.7.1-rc1 is prone to a path traversal flaw via ../ in a web skin name to access files outside of the intended skins directories.

The Apache project reports:

• DoS for HTTP/2 connections by crafted requests (CVE-2018-1333). By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. (low)
• mod_md, DoS via Coredumps on specially crafted requests (CVE-2018-8011). By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. (moderate)

Gitlab reports:

Remote Code Execution Vulnerability in GitLab Projects Import

Typo3 core team reports:

It has been discovered that TYPO3’s Salted Password system extension (which is a mandatory system component) is vulnerable to Authentication Bypass when using hashing methods which are related by PHP class inheritance. In standard TYPO3 core distributions stored passwords using the blowfish hashing algorithm can be overridden when using MD5 as the default hashing algorithm by just knowing a valid username. Per default the Portable PHP hashing algorithm (PHPass) is used which is not vulnerable.

Phar files (formerly known as "PHP archives") can act als self extracting archives which leads to the fact that source code is executed when Phar files are invoked. The Phar file format is not limited to be stored with a dedicated file extension - "bundle.phar" would be valid as well as "bundle.txt" would be. This way, Phar files can be obfuscated as image or text file which would not be denied from being uploaded and persisted to a TYPO3 installation. Due to a missing sanitization of user input, those Phar files can be invoked by manipulated URLs in TYPO3 backend forms. A valid backend user account is needed to exploit this vulnerability. In theory the attack vector would be possible in the TYPO3 frontend as well, however no functional exploit has been identified so far.

Failing to properly dissociate system related configuration from user generated configuration, the Form Framework (system extension "form") is vulnerable to SQL injection and Privilege Escalation. Basically instructions can be persisted to a form definition file that were not configured to be modified - this applies to definitions managed using the form editor module as well as direct file upload using the regular file list module. A valid backend user account as well as having system extension form activated are needed in order to exploit this vulnerability.

It has been discovered that the Form Framework (system extension "form") is vulnerable to Insecure Deserialization when being used with the additional PHP PECL package “yaml”, which is capable of unserializing YAML contents to PHP objects. A valid backend user account as well as having PHP setting "yaml.decode_php" enabled is needed to exploit this vulnerability.

The phpMyAdmin development team reports:

Summary

XSS in Designer feature

Description

A Cross-Site Scripting vulnerability was found in the Designer feature, where an attacker can deliver a payload to a user through a specially-crafted database name.

Severity

We consider this attack to be of moderate severity.

Summary

File inclusion and remote code execution attack

Description

A flaw has been discovered where an attacker can include (view and potentially execute) files on the server.

The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages.

An attacker must be authenticated, except in these situations:

• $cfg['AllowArbitraryServer'] = true: attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin
• $cfg['ServerDefault'] = 0: this bypasses the login and runs the vulnerable code without any authentication

Severity

We consider this to be severe.

Mitigation factor

Configuring PHP with a restrictive `open_basedir` can greatly restrict an attacker's ability to view files on the server. Vulnerable systems should not be run with the phpMyAdmin directives $cfg['AllowArbitraryServer'] = true or $cfg['ServerDefault'] = 0

Problem Description:

A subset of Intel processors can allow a local thread to infer data from another thread through a speculative execution side channel when Lazy FPU state restore is used.

Impact:

Any local thread can potentially read FPU state information from other threads running on the host. This could include cryptographic keys when the AES-NI CPU feature is present.

GraphicsMagick reports:

Multiple vulnerabilities have been found in GraphicsMagick 1.3.26 or earlier. Please refer to the CVE list for details.

SchedMD reports:

Insecure handling of user_name and gid fields (CVE-2018-10995)

While fixes are only available for the supported 17.02 and 17.11 releases, it is believed that similar vulnerabilities do affect past versions as well. The only resolution is to upgrade Slurm to a fixed release.

Node.js reports:

Denial of Service Vulnerability in HTTP/2 (CVE-2018-7161)

All versions of 8.x and later are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node server providing an http2 server to crash. This can be accomplished by interacting with the http2 server in a manner that triggers a cleanup bug where objects are used in native code after they are no longer available. This has been addressed by updating the http2 implementation. Thanks to Jordan Zebor at F5 Networks for reporting this issue.

Denial of Service, nghttp2 dependency (CVE-2018-1000168)

All versions of 9.x and later are vulnerable and the severity is HIGH. Under certain conditions, a malicious client can trigger an uninitialized read (and a subsequent segfault) by sending a malformed ALTSVC frame. This has been addressed through an by updating nghttp2.

Denial of Service Vulnerability in TLS (CVE-2018-7162)

All versions of 9.x and later are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node process which provides an http server supporting TLS server to crash. This can be accomplished by sending duplicate/unexpected messages during the handshake. This vulnerability has been addressed by updating the TLS implementation. Thanks to Jordan Zebor at F5 Networks all of his help investigating this issue with the Node.js team.

Memory exhaustion DoS on v9.x (CVE-2018-7164)

Versions 9.7.0 and later are vulnerable and the severity is MEDIUM. A bug introduced in 9.7.0 increases the memory consumed when reading from the network into JavaScript using the net.Socket object directly as a stream. An attacker could use this cause a denial of service by sending tiny chunks of data in short succession. This vulnerability was restored by reverting to the prior behaviour.

Calls to Buffer.fill() and/or Buffer.alloc() may hang (CVE-2018-7167)

Calling Buffer.fill() or Buffer.alloc() with some parameters can lead to a hang which could result in a Denial of Service. In order to address this vulnerability, the implementations of Buffer.alloc() and Buffer.fill() were updated so that they zero fill instead of hanging in these cases.

Jason A. Donenfeld reports:

Markus Brinkmann discovered that [the] parsing of gpg command line output with regexes isn't anchored to the beginning of the line, which means an attacker can generate a malicious key that simply has the verification string as part of its username.

This has a number of nasty consequences:

• an attacker who manages to write into your ~/.password-store and also inject a malicious key into your keyring can replace your .gpg-id key and have your passwords encrypted under additional keys;
• if you have extensions enabled (disabled by default), an attacker who manages to write into your ~/.password-store and also inject a malicious key into your keyring can replace your extensions and hence execute code.

GnuPG reports:

Mitigate a local side-channel attack on ECDSA signature as described in the white paper "Return on the Hidden Number Problem".

The OpenSSL project reports:

During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack.

The Asterisk project reports:

When endpoint specific ACL rules block a SIP request they respond with a 403 forbidden. However, if an endpoint is not identified then a 401 unauthorized response is sent. This vulnerability just discloses which requests hit a defined endpoint. The ACL rules cannot be bypassed to gain access to the disclosed endpoints.

The Asterisk project reports:

When connected to Asterisk via TCP/TLS if the client abruptly disconnects, or sends a specially crafted message then Asterisk gets caught in an infinite loop while trying to read the data stream. Thus rendering the system as unusable.

Corelight reports:

Bro 2.5.4 primarily fixes security issues

Multiple fixes and improvements to BinPAC generated code related to array parsing, with potential impact to all Bro's BinPAC-generated analyzers in the form of buffer over-reads or other invalid memory accesses depending on whether a particular analyzer incorrectly assumed that the evaulated-array-length expression is actually the number of elements that were parsed out from the input.

The NCP analyzer (not enabled by default and also updated to actually work with newer Bro APIs in the release) performed a memory allocation based directly on a field in the input packet and using signed integer storage. This could result in a signed integer overflow and memory allocations of negative or very large size, leading to a crash or memory exhaustion. The new NCP::max_frame_size tuning option now limits the maximum amount of memory that can be allocated.

The Git community reports:

Insufficient validation of submodule names

The Git community reports:

• In affected versions of Git, code to sanity-check pathnames on NTFS can result in reading out-of-bounds memory.
• In affected versions of Git, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then appended to $GIT_DIR/modules, leading to directory traversal with "../" in a name. Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks are not obtained from a remote server.

strongSwan security team reports:

• A denial-of-service vulnerability in the IKEv2 key derivation was fixed if the openssl plugin is used in FIPS mode and HMAC-MD5 is negotiated as PRF (which is not FIPS-compliant). So this should only affect very specific setups, but in such configurations all strongSwan versions since 5.0.1 may be affected.
• A denial-of-service vulnerability in the stroke plugin was fixed. When reading a message from the socket the plugin did not check the received length. Unless a group is configured, root privileges are required to access that socket, so in the default configuration this shouldn't be an issue, but all strongSwan versions may be affected.

ISC reports:

An error in zone database reference counting can lead to an assertion failure if a server which is running an affected version of BIND attempts several transfers of a slave zone in quick succession.

A problem with the implementation of the new serve-stale feature in BIND 9.12 can lead to an assertion failure in rbtdb.c, even when stale-answer-enable is off. Additionally, problematic interaction between the serve-stale feature and NSEC aggressive negative caching can in some cases cause undesirable behavior from named, such as a recursion loop or excessive logging.

cURL security problems:

CVE-2018-1000300: FTP shutdown response buffer overflow

curl might overflow a heap based memory buffer when closing down an FTP connection with very long server command replies.

When doing FTP transfers, curl keeps a spare "closure handle" around internally that will be used when an FTP connection gets shut down since the original curl easy handle is then already removed.

FTP server response data that gets cached from the original transfer might then be larger than the default buffer size (16 KB) allocated in the "closure handle", which can lead to a buffer overwrite. The contents and size of that overwrite is controllable by the server.

This situation was detected by an assert() in the code, but that was of course only preventing bad stuff in debug builds. This bug is very unlikely to trigger with non-malicious servers.

We are not aware of any exploit of this flaw.

CVE-2018-1000301: RTSP bad headers buffer over-read

curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded content.

When servers send RTSP responses back to curl, the data starts out with a set of headers. curl parses that data to separate it into a number of headers to deal with those appropriately and to find the end of the headers that signal the start of the "body" part.

The function that splits up the response into headers is called Curl_http_readwrite_headers() and in situations where it can't find a single header in the buffer, it might end up leaving a pointer pointing into the buffer instead of to the start of the buffer which then later on may lead to an out of buffer read when code assumes that pointer points to a full buffer size worth of memory to use.

This could potentially lead to information leakage but most likely a crash/denial of service for applications if a server triggers this flaw.

We are not aware of any exploit of this flaw.

Sebastian Ramacher reports:

A stack-based buffer over-read in the ParseRiffHeaderConfig function of cli/riff.c file of WavPack 5.1.0 allows a remote attacker to cause a denial-of-service attack or possibly have unspecified other impact via a maliciously crafted RF64 file.

The ParseDsdiffHeaderConfig function of the cli/dsdiff.c file of WavPack 5.1.0 allows a remote attacker to cause a denial-of-service (heap-based buffer over-read) or possibly overwrite the heap via a maliciously crafted DSDIFF file.

The ParseCaffHeaderConfig function of the cli/caff.c file of WavPack 5.1.0 allows a remote attacker to cause a denial-of-service (global buffer over-read), or possibly trigger a buffer overflow or incorrect memory allocation, via a maliciously crafted CAF file.

Thuan Pham reports:

An issue was discovered in WavPack 5.1.0 and earlier for WAV input. Out-of-bounds writes can occur because ParseRiffHeaderConfig in riff.c does not validate the sizes of unknown chunks before attempting memory allocation, related to a lack of integer-overflow protection within a bytes_to_copy calculation and subsequent malloc call, leading to insufficient memory allocation.

Jenkins developers report:

The agent to master security subsystem ensures that the Jenkins master is protected from maliciously configured agents. A path traversal vulnerability allowed agents to escape whitelisted directories to read and write to files they should not be able to access.

Black Duck Hub Plugin's API endpoint was affected by an XML External Entity (XXE) processing vulnerability. This allowed an attacker with Overall/Read access to have Jenkins parse a maliciously crafted file that uses external entities for extraction of secrets from the Jenkins master, server-side request forgery, or denial-of-service attacks.

Several other lower severity issues were reported, see reference url for details.

Summary

CSRF vulnerability allowing arbitrary SQL execution

Description

By deceiving a user to click on a crafted URL, it is possible for an attacker to execute arbitrary SQL commands.

Severity

We consider this vulnerability to be critical.

The Drupal security team reports:

CKEditor, a third-party JavaScript library included in Drupal core, has fixed a cross-site scripting (XSS) vulnerability. The vulnerability stemmed from the fact that it was possible to execute XSS inside CKEditor when using the image2 plugin (which Drupal 8 core also uses).

The OpenSSL project reports:

The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key.

Drupal Security Team reports:

CVE-2018-7600: Drupal before 7.58, 8.x before 8.3.9, 8.4.x before 8.4.6, and 8.5.x before 8.5.1 allows remote attackers to execute arbitrary code because of an issue affecting multiple subsystems with default or common module configurations.

perldelta:

CVE-2018-6797: heap-buffer-overflow (WRITE of size 1) in S_regatom (regcomp.c)

A crafted regular expression could cause a heap buffer write overflow, with control over the bytes written. [perl #132227]

CVE-2018-6798: Heap-buffer-overflow in Perl__byte_dump_string (utf8.c)

Matching a crafted locale dependent regular expression could cause a heap buffer read overflow and potentially information disclosure. [perl #132063]

CVE-2018-6913: heap-buffer-overflow in S_pack_rec

pack() could cause a heap buffer write overflow with a large item count. [perl #131844]

Robert Foggia via NetBSD GNATS reports:

The ipsec-tools racoon daemon contains a remotely exploitable computational complexity attack when parsing and storing isakmp fragments. The implementation permits a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending isakmp fragment packets in a particular order such that the worst-case computational complexity is realized in the algorithm utilized to determine if reassembly of the fragments can take place.

nghttp2 blog:

If ALTSVC frame is received by libnghttp2 and it is larger than it can accept, the pointer field which points to ALTSVC frame payload is left NULL. Later libnghttp2 attempts to access another field through the pointer, and gets segmentation fault.

ALTSVC frame is defined by RFC 7838.

The largest frame size libnghttp2 accept is by default 16384 bytes.

Receiving ALTSVC frame is disabled by default. Application has to enable it explicitly by calling nghttp2_option_set_builtin_recv_extension_type(opt, NGHTTP2_ALTSVC).

Transmission of ALTSVC is always enabled, and it does not cause this vulnerability.

ALTSVC frame is expected to be sent by server, and received by client as defined in RFC 7838.

Client and server are both affected by this vulnerability if the reception of ALTSVC frame is enabled. As written earlier, it is useless to enable reception of ALTSVC frame on server side. So, server is generally safe unless application accidentally enabled the reception of ALTSVC frame.

Upstream reports:

This update primarily fixes a recently discovered IMAP-cmd-injection vulnerability caused by insufficient input validation within the archive plugin. Details about the vulnerability are published under CVE-2018-9846.

Jenkins developers report:

The Jenkins CLI sent different error responses for commands with view and agent arguments depending on the existence of the specified views or agents to unauthorized users. This allowed attackers to determine whether views or agents with specified names exist.

The Jenkins CLI now returns the same error messages to unauthorized users independent of the existence of specified view or agent names

Some JavaScript confirmation dialogs included the item name in an unsafe manner, resulting in a possible cross-site scripting vulnerability exploitable by users with permission to create or configure items.

JavaScript confirmation dialogs that include the item name now properly escape it, so it can be safely displayed.

GitLab reports:

Confidential issue comments in Slack, Mattermost, and webhook integrations.

Persistent XSS in milestones data-milestone-id.

Persistent XSS in filename of merge request.

Problem Description:

The length field of the option header does not count the size of the option header itself. This causes a problem when the length is zero, the count is then incremented by zero, which causes an infinite loop.

In addition there are pointer/offset mistakes in the handling of IPv4 options.

Impact:

A remote attacker who is able to send an arbitrary packet, could cause the remote target machine to crash.

Problem Description:

Insufficient validation of user-provided font parameters can result in an integer overflow, leading to the use of arbitrary kernel memory as glyph data. Characters that reference this data can be displayed on the screen, effectively disclosing kernel memory.

Impact:

Unprivileged users may be able to access privileged kernel data.

Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.

Ruby news:

CVE-2017-17742: HTTP response splitting in WEBrick

If a script accepts an external input and outputs it without modification as a part of HTTP responses, an attacker can use newline characters to deceive the clients that the HTTP response header is stopped at there, and can inject fake HTTP responses after the newline characters to show malicious contents to the clients.

CVE-2018-6914: Unintentional file and directory creation with directory traversal in tempfile and tmpdir

Dir.mktmpdir method introduced by tmpdir library accepts the prefix and the suffix of the directory which is created as the first parameter. The prefix can contain relative directory specifiers "../", so this method can be used to target any directory. So, if a script accepts an external input as the prefix, and the targeted directory has inappropriate permissions or the ruby process has inappropriate privileges, the attacker can create a directory or a file at any directory.

CVE-2018-8777: DoS by large request in WEBrick

If an attacker sends a large request which contains huge HTTP headers, WEBrick try to process it on memory, so the request causes the out-of-memory DoS attack.

CVE-2018-8778: Buffer under-read in String#unpack

String#unpack receives format specifiers as its parameter, and can be specified the position of parsing the data by the specifier @. If a big number is passed with @, the number is treated as the negative value, and out-of-buffer read is occurred. So, if a script accepts an external input as the argument of String#unpack, the attacker can read data on heaps.

CVE-2018-8779: Unintentional socket creation by poisoned NUL byte in UNIXServer and UNIXSocket

UNIXServer.open accepts the path of the socket to be created at the first parameter. If the path contains NUL (\0) bytes, this method recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of this method, the attacker can make the socket file in the unintentional path. And, UNIXSocket.open also accepts the path of the socket to be created at the first parameter without checking NUL bytes like UNIXServer.open. So, if a script accepts an external input as the argument of this method, the attacker can accepts the socket file in the unintentional path.

CVE-2018-8780: Unintentional directory traversal by poisoned NUL byte in Dir

Dir.open, Dir.new, Dir.entries and Dir.empty? accept the path of the target directory as their parameter. If the parameter contains NUL (\0) bytes, these methods recognize that the path is completed before the NUL bytes. So, if a script accepts an external input as the argument of these methods, the attacker can make the unintentional directory traversal.

Node.js reports:

Node.js Inspector DNS rebinding vulnerability (CVE-2018-7160)

Node.js 6.x and later include a debugger protocol (also known as "inspector") that can be activated by the --inspect and related command line flags. This debugger service was vulnerable to a DNS rebinding attack which could be exploited to perform remote code execution.

'path' module regular expression denial of service (CVE-2018-7158)

The 'path' module in the Node.js 4.x release line contains a potential regular expression denial of service (ReDoS) vector. The code in question was replaced in Node.js 6.x and later so this vulnerability only impacts all versions of Node.js 4.x.

Spaces in HTTP Content-Length header values are ignored (CVE-2018-7159)

The HTTP parser in all current versions of Node.js ignores spaces in the Content-Length header, allowing input such as Content-Length: 1 2 to be interpreted as having a value of 12. The HTTP specification does not allow for spaces in the Content-Length value and the Node.js HTTP parser has been brought into line on this particular difference.

The WebKit team reports many vulnerabilities.

• [823553] Various fixes from internal audits, fuzzing and other initiatives

The OpenSSL project reports:

• Constructed ASN.1 types with a recursive definition could exceed the stack (CVE-2018-0739)
  Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe.
• rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
  There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation).

GitLab reports:

SSRF in services and web hooks

There were multiple server-side request forgery issues in the Services feature. An attacker could make requests to servers within the same network of the GitLab instance. This could lead to information disclosure, authentication bypass, or potentially code execution. This issue has been assigned CVE-2018-8801.

Gitlab Auth0 integration issue

There was an issue with the GitLab omniauth-auth0 configuration which resulted in the Auth0 integration signing in the wrong users.

MITRE reports:

SQLite databases whose schema is corrupted using a CREATE TABLE AS statement could cause a NULL pointer dereference, related to build.c and prepare.c.

Sanitize release:

Fixed an HTML injection vulnerability that could allow XSS.

When Sanitize <= 4.6.2 is used in combination with libxml2 >= 2.9.2, a specially crafted HTML fragment can cause libxml2 to generate improperly escaped output, allowing non-whitelisted attributes to be used on whitelisted elements.

Sanitize now performs additional escaping on affected attributes to prevent this.

GitHub issue:

This issue has been created for public disclosure of an XSS / code injection vulnerability that was responsibly reported by the Shopify Application Security Team.

Loofah allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments.

MITRE reports:

In Jupyter Notebook before 5.4.1, a maliciously forged notebook file can bypass sanitization to execute JavaScript in the notebook context. Specifically, invalid HTML is 'fixed' by jQuery after sanitization, making it dangerous.

Florian Grunow reports:

An attacker able to exploit this vulnerability can extract files of the server the application is running on. This may include configuration files, log files and additionally all files that are readable for all users on the system. This issue is post-authentication. That means an attacker would need valid credentials for the application to log in or needs to exploit an additional vulnerability of which we are not aware of at this point of time.

An attacker would also be able to delete files on the system, if the user running the application has the rights to do so.

Does this issue affect me?

Likely yes, if you are using Squirrelmail. We checked the latest development version, which is 1.5.2-svn and the latest version available for download at this point of time, 1.4.22. Both contain the vulnerable code.

SchedMD reports:

Several issues were discovered with incomplete sanitization of user-provided text strings, which could potentially lead to SQL injection attacks against SlurmDBD itself. Such exploits could lead to a loss of accounting data, or escalation of user privileges on the cluster.

NVD reports:

Xiph.Org libvorbis 1.3.5 allows Remote Code Execution upon freeing uninitialized memory in the function vorbis_analysis_headerout() in info.c when vi->channels<=0, a similar issue to Mozilla bug 550184.

In Xiph.Org libvorbis 1.3.5, an out-of-bounds array read vulnerability exists in the function mapping0_forward() in mapping0.c, which may lead to DoS when operating on a crafted audio file with vorbis_analysis().

The Mozilla Foundation reports:

CVE-2018-5146: Out of bounds memory write in libvorbis

An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest.

CVE-2018-5147: Out of bounds memory write in libtremor

The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of libvorbis on Android and ARM platforms.

Theodore Y. Ts'o reports:

Fixed some potential buffer overrun bugs in the blkid library and in the fsck program.

Problem Description:

A number of issues relating to speculative execution were found last year and publicly announced January 3rd. Two of these, known as Meltdown and Spectre V2, are addressed here.

CVE-2017-5754 (Meltdown) - ------------------------

This issue relies on an affected CPU speculatively executing instructions beyond a faulting instruction. When this happens, changes to architectural state are not committed, but observable changes may be left in micro- architectural state (for example, cache). This may be used to infer privileged data.

CVE-2017-5715 (Spectre V2) - --------------------------

Spectre V2 uses branch target injection to speculatively execute kernel code at an address under the control of an attacker.

Impact:

An attacker may be able to read secret data from the kernel or from a process when executing untrusted code (for example, in a web browser).

Problem Description:

Due to a lack of strict checking, an attacker from a trusted host can send a specially constructed IP packet that may lead to a system crash.

Additionally, a use-after-free vulnerability in the AH handling code could cause unpredictable results.

Impact:

Access to out of bounds or freed mbuf data can lead to a kernel panic or other unpredictable results.

Adobe reports:

• This update resolves a use-after-free vulnerability that could lead to remote code execution (CVE-2018-4919).
• This update resolves a type confusion vulnerability that could lead to remote code execution (CVE-2018-4920).

Simon Butcher reports:

• When the truncated HMAC extension is enabled and CBC is used, sending a malicious application packet can be used to selectively corrupt 6 bytes on the peer's heap, potentially leading to a crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS.
• When RSASSA-PSS signature verification is enabled, sending a maliciously constructed certificate chain can be used to cause a buffer overflow on the peer's stack, potentially leading to crash or remote code execution. This can be triggered remotely from either side in both TLS and DTLS.

ISC reports:

Failure to properly bounds check a buffer used for processing DHCP options allows a malicious server (or an entity masquerading as a server) to cause a buffer overflow (and resulting crash) in dhclient by sending a response containing a specially constructed options section.

A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash.

Strongswan Release Notes reports:

Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS signatures that was caused by insufficient input validation. One of the configurable parameters in algorithm identifier structures for RSASSA-PSS signatures is the mask generation function (MGF). Only MGF1 is currently specified for this purpose. However, this in turn takes itself a parameter that specifies the underlying hash function. strongSwan's parser did not correctly handle the case of this parameter being absent, causing an undefined data read. his vulnerability has been registered as CVE-2018-6459.

Laurent Delosieres, Secunia Research at Flexera Software reports:

Secunia Research has discovered a vulnerability in libsndfile, which can be exploited by malicious people to disclose potentially sensitive information.

The Apache Software Foundation reports:

Security constraints defined by annotations of Servlets were only applied once a Servlet had been loaded. Because security constraints defined in this way apply to the URL pattern and any URLs below that point, it was possible - depending on the order Servlets were loaded - for some security constraints not to be applied. This could have exposed resources to users who were not authorised to access them.

The URL pattern of "" (the empty string) which exactly maps to the context root was not correctly handled when used as part of a security constraint definition. This caused the constraint to be ignored. It was, therefore, possible for unauthorised users to gain access to web application resources that should have been protected. Only security constraints with a URL pattern of the empty string were affected.

The XML processing performed by the Service Provider software has been found to be vulnerable to new flaws similar in nature to the one addressed in an advisory last month.

These bugs involve the use of other XML constructs rather than entity references, and therefore required additional mitigation once discovered. As with the previous issue, this flaw allows for changes to an XML document that do not break a digital signature but can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.

As before, the use of XML Encryption is a significant mitigation, but we have not dismissed the possibility that attacks on the Response "envelope" may be possible, in both the original and this new case. No actual attacks of this nature are known, so deployers should prioritize patching systems that expect to handle unencrypted SAML assertions.

An updated version of XMLTooling-C (V1.6.4) is available that protects against these new attacks, and should help prevent similar vulnerabilities in the future.

Unlike the previous case, these bugs are NOT prevented by any existing Xerces-C parser version on any platform and cannot be addressed by any means other than the updated XMLTooling-C library.

The Service Provider software relies on a generic XML parser to process SAML responses and there are limitations in older versions of the parser that make it impossible to fully disable Document Type Definition (DTD) processing.

Through addition/manipulation of a DTD, it's possible to make changes to an XML document that do not break a digital signature but are mishandled by the SP and its libraries. These manipulations can alter the user data passed through to applications behind the SP and result in impersonation attacks and exposure of protected information.

While newer versions of the xerces-c3 parser are configured by the SP into disallowing the use of a DTD via an environment variable, this feature is not present in the xerces-c3 parser before version 3.1.4, so an additional fix is being provided now that an actual DTD exploit has been identified. Xerces-c3-3.1.4 was committed to the ports tree already on 2016-07-26.

Hank Leininger reports:

Bugs in Git, Subversion, and Mercurial were just announced and patched which allowed arbitrary local command execution if a malicious name was used for the remote server, such as starting with - to pass options to the ssh client: git clone ssh://-oProxyCommand=some-command... CVS has a similar problem with the -d option:

Tested vanilla CVS 1.12.13, and Gentoo CVS 1.12.12-r11.

LibreOffice reports:

LibreOffice Calc supports a WEBSERVICE function to obtain data by URL. Vulnerable versions of LibreOffice allow WEBSERVICE to take a local file URL (e.g file://) which can be used to inject local files into the spreadsheet without warning the user. Subsequent formulas can operate on that inserted data and construct a remote URL whose path leaks the local data to a remote attacker.

In later versions of LibreOffice without this flaw, WEBSERVICE has now been limited to accessing http and https URLs along with bringing WEBSERVICE URLs under LibreOffice Calc's link management infrastructure.

Note: This vulnerability has been identified upstream as CVE-2018-1055, but NVD/Mitre are advising it's a reservation duplicate of CVE-2018-6871 which should be used instead.

Louis Dion-Marcil reports:

Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses.

This problem allows a remote server delivering certain ESI response syntax to trigger a denial of service for all clients accessing the Squid service.

Due to unrelated changes Squid-3.5 has become vulnerable to some regular ESI server responses also triggering this issue.

This problem is limited to the Squid custom ESI parser. Squid built to use libxml2 or libexpat XML parsers do not have this problem.

Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses or downloading intermediate CA certificates.

This problem allows a remote client delivering certain HTTP requests in conjunction with certain trusted server responses to trigger a denial of service for all clients accessing the Squid service.

The Asterisk project reports:

AST-2018-004 - When processing a SUBSCRIBE request the res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request. This code did not limit the number of headers it processed despite having a fixed limit of 32. If more than 32 Accept headers were present the code would write outside of its memory and cause a crash.

AST-2018-005 - A crash occurs when a number of authenticated INVITE messages are sent over TCP or TLS and then the connection is suddenly closed. This issue leads to a segmentation fault.

The Asterisk project reports:

AST-2018-002 - By crafting an SDP message with an invalid media format description Asterisk crashes when using the pjsip channel driver because pjproject's sdp parsing algorithm fails to catch the invalid media format description.

AST-2018-003 - By crafting an SDP message body with an invalid fmtp attribute Asterisk crashes when using the pjsip channel driver because pjproject's fmtp retrieval function fails to check if fmtp value is empty (set empty if previously parsed as invalid).

Jenkins did not properly prevent specifying relative paths that escape a base directory for URLs accessing plugin resource files. This allowed users with Overall/Read permission to download files from the Jenkins master they should not have access to.

Mitre reports:

bchunk 1.2.0 and 1.2.1 is vulnerable to an "Access violation near NULL on destination operand" and crash when processing a malformed CUE (.cue) file.

Mitre reports:

bchunk 1.2.0 and 1.2.1 is vulnerable to a heap-based buffer overflow (with a resultant invalid free) and crash when processing a malformed CUE (.cue) file.

Mitre reports:

bchunk 1.2.0 and 1.2.1 vulnerable to a heap-based buffer overflow and crash when processing a malformed CUE (.cue) file.

Uwsgi developers report:

It was discovered that the uwsgi_expand_path function in utils.c in Unbit uWSGI, an application container server, has a stack-based buffer overflow via a large directory length that can cause a denial-of-service (application crash) or stack corruption.

Python issue:

There is a possible integer overflow in PyString_DecodeEscape function of the file stringobject.c, which can be abused to gain a heap overflow, possibly leading to arbitrary code execution.

MITRE reports:

JSONRPC vulnerability

X-cela reports:

Calls into build_benocde that use %zu could crash on 64 bit machines due to the size change of size_t. Someone can force READ_ENC_IA to fail allowing an internal_error to be thrown and bring down the client.

Exim developers report:

There is a buffer overflow in base64d(), if some pre-conditions are met. Using a handcrafted message, remote code execution seems to be possible.

MITRE reports:

Insufficient exception handling in the method NCompress::NRar3::CDecoder::Code of 7-Zip before 18.00 and p7zip can lead to multiple memory corruptions within the PPMd code, alows remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.

MITRE reports:

Heap-based buffer overflow in the NCompress::NShrink::CDecoder::CodeReal method in 7-Zip before 18.00 and p7zip allows remote attackers to cause a denial of service (out-of-bounds write) or potentially execute arbitrary code via a crafted ZIP archive.

mpv developers report:

mpv through 0.28.0 allows remote attackers to execute arbitrary code via a crafted web site, because it reads HTML documents containing VIDEO elements, and accepts arbitrary URLs in a src attribute without a protocol whitelist in player/lua/ytdl_hook.lua. For example, an av://lavfi:ladspa=file= URL signifies that the product should call dlopen on a shared object file located at an arbitrary local pathname. The issue exists because the product does not consider that youtube-dl can provide a potentially unsafe URL.

Mark Sapiro reports:

An XSS vulnerability in the user options CGI could allow a crafted URL to execute arbitrary javascript in a user's browser. A related issue could expose information on a user's options page without requiring login.

The PostgreSQL project reports:

• CVE-2018-1052: Fix the processing of partition keys containing multiple expressions (only for PostgreSQL-10.x)

CVE-2018-5122: Potential integer overflow in DoCrypt

Django release notes:

CVE-2018-6188: Information leakage in AuthenticationForm

A regression in Django 1.11.8 made AuthenticationForm run its confirm_login_allowed() method even if an incorrect password is entered. This can leak information about a user, depending on what messages confirm_login_allowed() raises. If confirm_login_allowed() isn't overridden, an attacker enter an arbitrary username and see if that user has been set to is_active=False. If confirm_login_allowed() is overridden, more sensitive details could be leaked.

This issue is fixed with the caveat that AuthenticationForm can no longer raise the "This account is inactive." error if the authentication backend rejects inactive users (the default authentication backend, ModelBackend, has done that since Django 1.10). This issue will be revisited for Django 2.1 as a fix to address the caveat will likely be too invasive for inclusion in older versions.

Tatsuya Kinoshita reports:

CVE-2018-6196 * table.c: Prevent negative indent value in feed_table_block_tag().

CVE-2018-6197 * form.c: Prevent invalid columnPos() call in formUpdateBuffer().
