OTRS reports:
An attacker who is logged into OTRS as an agent can request special URLs from OTRS which can lead to the execution of shell commands with the permissions of the web server user.
An attacker who is logged into OTRS as a customer can use the ticket search form to disclose internal article information of their customer tickets.
An attacker who is logged into OTRS as an agent can manipulate form parameters and execute arbitrary shell commands with the permissions of the OTRS or web server user.
An attacker can send a specially prepared email to an OTRS system. If this system has cookie support disabled, and a logged in agent clicks a link in this email, the session information could be leaked to external systems, allowing the attacker to take over the agent’s session.
The Legion of the Bouncy Castle reports:
Release: 1.59
CVE-2017-13098 ("ROBOT"), a Bleichenbacher oracle in TLS when RSA key exchange is negotiated. This potentially affected BCJSSE servers and any other TLS servers configured to use JCE for the underlying crypto - note the two TLS implementations using the BC lightweight APIs are not affected by this.

We consider this vulnerability to be critical.
The Asterisk project reports:
A select set of SIP messages create a dialog in Asterisk. Those SIP messages must contain a contact header. For those messages, if the header was not present and using the PJSIP channel driver, it would cause Asterisk to crash. The severity of this vulnerability is somewhat mitigated if authentication is enabled. If authentication is enabled a user would have to first be authorized before reaching the crash point.
The MariaDB project reports:
Fixes for the following security vulnerabilities: CVE-2017-15365
Jeriko One reports:
The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon.
The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions.
The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does not check for fnamecmp filenames in the daemon_filter_list data structure (in the recv_files function in receiver.c) and also does not apply the sanitize_paths protection mechanism to pathnames found in "xname follows" strings (in the read_ndx_and_attrs function in rsync.c), which allows remote attackers to bypass intended access restrictions.
Etienne Stalmans from the Heroku product security team reports:
There is a command injection vulnerability in Net::FTP bundled with Ruby.
Net::FTP#get,getbinaryfile,gettextfile,put,putbinaryfile, andputtextfileuseKernel#opento open a local file. If thelocalfileargument starts with the pipe character"|", the command following the pipe character is executed. The default value oflocalfileisFile.basename(remotefile), so malicious FTP servers could cause arbitrary command execution.
Phusion reports:
The cPanel Security Team discovered a vulnerability in Passenger that allows users to list the contents of arbitrary files on the system. CVE-2017-16355 has been assigned to this issue.
the freedesktop.org project reports:
A non-privileged X client can instruct X server running under root to open any file by creating own directory with "fonts.dir", "fonts.alias" or any font file being a symbolic link to any other file in the system. X server will then open it. This can be issue with special files such as /dev/watchdog.
The freedesktop.org project reports:
If a pattern contains '?' character, any character in the string is skipped, even if it is '\0'. The rest of the matching then reads invalid memory.
Without the checks a malformed PCF file can cause the library to make atom from random heap memory that was behind the `strings` buffer. This may crash the process or leak information.
The freedesktop.org project reports:
It is possible to trigger heap overflows due to an integer overflow while parsing images and a signedness issue while parsing comments.
The integer overflow occurs because the chosen limit 0x10000 for dimensions is too large for 32 bit systems, because each pixel takes 4 bytes. Properly chosen values allow an overflow which in turn will lead to less allocated memory than needed for subsequent reads.
The signedness bug is triggered by reading the length of a comment as unsigned int, but casting it to int when calling the function XcursorCommentCreate. Turning length into a negative value allows the check against XCURSOR_COMMENT_MAX_LEN to pass, and the following addition of sizeof (XcursorComment) + 1 makes it possible to allocate less memory than needed for subsequent reads.
MITRE reports:
gozilla.c in GNU GLOBAL 4.8.6 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL.
The Jenkins project reports:
A race condition during Jenkins startup could result in the wrong order of execution of commands during initialization.
On Jenkins 2.81 and newer, including LTS 2.89.1, this could in rare cases (we estimate less than 20% of new instances) result in failure to initialize the setup wizard on the first startup.
There is a very short window of time after startup during which Jenkins may no longer show the "Please wait while Jenkins is getting ready to work" message, but Cross-Site Request Forgery (CSRF) protection may not yet be effective.
Node.js reports:
Data Confidentiality/Integrity Vulnerability - CVE-2017-15896
Node.js was affected by OpenSSL vulnerability CVE-2017-3737 in regards to the use of SSL_read() due to TLS handshake failure. The result was that an active network attacker could send application data to Node.js using the TLS or HTTP2 modules in a way that bypassed TLS authentication and encryption.
Uninitialized buffer vulnerability - CVE-2017-15897
Node.js had a bug in versions 8.X and 9.X which caused buffers to not be initialized when the encoding for the fill value did not match the encoding specified. For example, 'Buffer.alloc(0x100, "This is not correctly encoded", "hex");' The buffer implementation was updated such that the buffer will be initialized to all zeros in these cases.
Also included in OpenSSL update - CVE 2017-3738
Note that CVE 2017-3738 of OpenSSL-1.0.2 affected Node but it was low severity.

The Asterisk project reports:
If a compound RTCP packet is received containing more than one report (for example a Receiver Report and a Sender Report) the RTCP stack will incorrectly store report information outside of allocated memory potentially causing a crash.
libxml2 developers report:
The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4 allows attackers to cause a denial of service (buffer over-read) or information disclosure.
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for libxml2 Bug 759398.
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictAddString function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for CVE-2016-1839.
Invoking SSL_read()/SSL_write() while in an error state causes data to be passed without being decrypted/encrypted directly from the SSL/TLS record layer.
In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. [CVE-2017-3737]
There is an overflow bug in the x86_64 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). [CVE-2017-3738] This bug only affects FreeBSD 11.x.
Applications with incorrect error handling may inappropriately pass unencrypted data. [CVE-2017-3737]
Mishandling of carry propagation will produce incorrect output, and make it easier for a remote attacker to obtain sensitive private-key information. No EC algorithms are affected and analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.
Attacks against DH1024 are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701. [CVE-2017-3738]

The OpenSSL project reports:
- Read/write after SSL object in error state (CVE-2017-3737)
OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer.- 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. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH1024 are considered just feasible, because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701.
If an X.509 certificate has a malformed IPAddressFamily extension, OpenSSL could do a one-byte buffer overread. [CVE-2017-3735]
There is a carry propagating bug in the x86_64 Montgomery squaring procedure. This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen. [CVE-2017-3736] This bug only affects FreeBSD 11.x.
Application using OpenSSL may display erroneous certificate in text format. [CVE-2017-3735]
Mishandling of carry propagation will produce incorrect output, and make it easier for a remote attacker to obtain sensitive private-key information. No EC algorithms are affected, analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely.
Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. [CVE-2017-3736]
The kernel does not properly clear the memory of the kld_file_stat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible.
Some bytes from the kernel stack can be observed in userspace.
Named paths are globally scoped, meaning a process located in one jail can read and modify the content of POSIX shared memory objects created by a process in another jail or the host system.
A malicious user that has access to a jailed system is able to abuse shared memory by injecting malicious content in the shared memory region. This memory region might be executed by applications trusting the shared memory, like Squid.
This issue could lead to a Denial of Service or local privilege escalation.
Not all information in the struct ptrace_lwpinfo is relevant for the state of any thread, and the kernel does not fill the irrelevant bytes or short strings. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information of the kernel stack of the thread is possible from the debugger.
Some bytes from the kernel stack of the thread using ptrace(PT_LWPINFO) call can be observed in userspace.
A vulnerability was found in how a number of implementations can be triggered to reconfigure WPA/WPA2/RSN keys (TK, GTK, or IGTK) by replaying a specific frame that is used to manage the keys.
Such reinstallation of the encryption key can result in two different types of vulnerabilities: disabling replay protection and significantly reducing the security of encryption to the point of allowing frames to be decrypted or some parts of the keys to be determined by an attacker depending on which cipher is used.

If the chan_skinny (AKA SCCP protocol) channel driver is flooded with certain requests it can cause the asterisk process to use excessive amounts of virtual memory eventually causing asterisk to stop processing requests of any kind.
Exim developers team reports:
The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to cause a denial of service (infinite loop and stack exhaustion) via vectors involving BDAT commands and an improper check for a '.' character signifying the end of the content, related to the bdat_getc function.

The scp_v0s_accept function in the session manager uses an untrusted integer as a write length, which allows local users to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted input stream.
The cURL project reports:
- NTLM buffer overflow via integer overflow (CVE-2017-8816)
libcurl contains a buffer overrun flaw in the NTLM authentication code. The internal function Curl_ntlm_core_mk_ntlmv2_hash sums up the lengths of the user name + password (= SUM) and multiplies the sum by two (= SIZE) to figure out how large storage to allocate from the heap.- FTP wildcard out of bounds read (CVE-2017-8817)
libcurl contains a read out of bounds flaw in the FTP wildcard function. libcurl's FTP wildcard matching feature, which is enabled with the CURLOPT_WILDCARDMATCH option can use a built-in wildcard function or a user provided one. The built-in wildcard function has a flaw that makes it not detect the end of the pattern string if it ends with an open bracket ([) but instead it will continue reading the heap beyond the end of the URL buffer that holds the wildcard.- SSL out of buffer access (CVE-2017-8818)
libcurl contains an out boundary access flaw in SSL related code. When allocating memory for a connection (the internal struct called connectdata), a certain amount of memory is allocated at the end of the struct to be used for SSL related structs. Those structs are used by the particular SSL library libcurl is built to use. The application can also tell libcurl which specific SSL library to use if it was built to support more than one.

The Internet2 community reports:
The Shibboleth Service Provider software includes a MetadataProvider plugin with the plugin type "Dynamic" to obtain metadata on demand from a query server, in place of the more typical mode of downloading aggregates separately containing all of the metadata to load.
All the plugin types rely on MetadataFilter plugins to perform critical security checks such as signature verification, enforcement of validity periods, and other checks specific to deployments.
Due to a coding error, the "Dynamic" plugin fails to configure itself with the filters provided to it and thus omits whatever checks they are intended to perform, which will typically leave deployments vulnerable to active attacks involving the substitution of metadata if the network path to the query service is compromised.

Jenkins developers report:
Jenkins stores metadata related to people, which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping. This potentially resulted in a number of problems.
Autocompletion suggestions for text fields were not escaped, resulting in a persisted cross-site scripting vulnerability if the source for the suggestions allowed specifying text that includes HTML metacharacters like less-than and greater-than characters.
The Asterisk project reports:
A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. This then leads to file descriptors and RTP ports being leaked as well.
The Asterisk project reports:
No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. The earlier AST-2017-001 advisory for the CDR user field overflow was for the Party A buffer.
The Asterisk project reports:
By carefully crafting invalid values in the Cseq and the Via header port, pjprojects packet parsing code can create strings larger than the buffer allocated to hold them. This will usually cause Asterisk to crash immediately. The packets do not have to be authenticated.

Node.js reports:
Node.js was susceptible to a remote DoS attack due to a change that came in as part of zlib v1.2.9. In zlib v1.2.9 8 became an invalid value for the windowBits parameter and Node's zlib module will crash or throw an exception (depending on the version)
GitLab reports:
Cross-Site Scripting (XSS) vulnerability in the Markdown sanitization filter
Yasin Soliman via HackerOne reported a Cross-Site Scripting (XSS) vulnerability in the GitLab markdown sanitization filter. The sanitization filter was not properly stripping invalid characters from URL schemes and was therefore vulnerable to persistent XSS attacks anywhere Markdown was supported.
Cross-Site Scripting (XSS) vulnerability in search bar
Josh Unger reported a Cross-Site Scripting (XSS) vulnerability in the issue search bar. Usernames were not being properly HTML escaped inside the author filter would could allow arbitrary script execution.
Open redirect in repository git redirects
Eric Rafaloff via HackerOne reported that GitLab was vulnerable to an open redirect vulnerability when redirecting requests for repository names that include the git extension. GitLab was not properly removing dangerous parameters from the params field before redirecting which could allow an attacker to redirect users to arbitrary hosts.
Username changes could leave repositories behind
An internal code review discovered that a bug in the code that moves repositories during a username change could potentially leave behind projects, allowing an attacker who knows the previous username to potentially steal the contents of repositories on instances that are not configured with hashed namespaces.
The Apache Openofffice project reports:
CVE-2017-3157: Arbitrary file disclosure in Calc and Writer
By exploiting the way OpenOffice renders embedded objects, an attacker could craft a document that allows reading in a file from the user's filesystem. Information could be retrieved by the attacker by, e.g., using hidden sections to store the information, tricking the user into saving the document and convincing the user to sent the document back to the attacker.
The vulnerability is mitigated by the need for the attacker to know the precise file path in the target system, and the need to trick the user into saving the document and sending it back.
CVE-2017-9806: Out-of-Bounds Write in Writer's WW8Fonts Constructor
A vulnerability in the OpenOffice Writer DOC file parser, and specifically in the WW8Fonts Constructor, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
CVE-2017-12607: Out-of-Bounds Write in Impress' PPT Filter
A vulnerability in OpenOffice's PPT file parser, and specifically in PPTStyleSheet, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
CVE-2017-12608: Out-of-Bounds Write in Writer's ImportOldFormatStyles
A vulnerability in OpenOffice Writer DOC file parser, and specifically in ImportOldFormatStyles, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.
The cURL project reports:
libcurl contains a buffer overrun flaw in the IMAP handler.
An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function.
libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memory lies after (or just crash) and then deliver that to the application as if it was actually downloaded.
Frederik Deweerdt reports:
Multiple Denial-of-Service vulnerabilities exist in h2o workers - see references for full details.
CVE-2017-10868: Worker processes may crash when receiving a request with invalid framing.
CVE-2017-10869: The stack may overflow when proxying huge requests.
Irssi reports:
When installing themes with unterminated colour formatting sequences, Irssi may access data beyond the end of the string.
While waiting for the channel synchronisation, Irssi may incorrectly fail to remove destroyed channels from the query list, resulting in use after free conditions when updating the state later on.
Certain incorrectly formatted DCC CTCP messages could cause NULL pointer dereference.
Overlong nicks or targets may result in a NULL pointer dereference while splitting the message.
In certain cases Irssi may fail to verify that a Safe channel ID is long enough, causing reads beyond the end of the string.

MIT reports:
CVE-2017-11368:
In MIT krb5 1.7 and later, an authenticated attacker can cause an assertion failure in krb5kdc by sending an invalid S4U2Self or S4U2Proxy request.
CVE-2017-11462:
RFC 2744 permits a GSS-API implementation to delete an existing security context on a second or subsequent call to gss_init_sec_context() or gss_accept_sec_context() if the call results in an error. This API behavior has been found to be dangerous, leading to the possibility of memory errors in some callers. For safety, GSS-API implementations should instead preserve existing security contexts on error until the caller deletes them.
All versions of MIT krb5 prior to this change may delete acceptor contexts on error. Versions 1.13.4 through 1.13.7, 1.14.1 through 1.14.5, and 1.15 through 1.15.1 may also delete initiator contexts on error.
Oracle reports:

Solr developers report:
Lucene XML parser does not explicitly prohibit doctype declaration and expansion of external entities which leads to arbitrary HTTP requests to the local SOLR instance and to bypass all firewall restrictions.
Solr "RunExecutableListener" class can be used to execute arbitrary commands on specific events, for example after each update query. The problem is that such listener can be enabled with any parameters just by using Config API with add-listener command.
jenkins developers report:
A total of 11 issues are reported, please see reference URL for details.
The Xen project reports multiple vulnerabilities.
Mozilla reports:
During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash.
osip developers reports:
In libosip2 in GNU oSIP 4.1.0 and 5.0.0, a malformed SIP message can lead to a heap buffer overflow in the msg_osip_body_parse() function defined in osipparser2/osip_message_parse.c, resulting in a remote DoS.

tomcat developers reports:
When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet 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 cURL project reports:
FTP PWD response parser out of bounds read
libcurl may read outside of a heap allocated buffer when doing FTP.
When libcurl connects to an FTP server and successfully logs in (anonymous or not), it asks the server for the current directory with the PWD command. The server then responds with a 257 response containing the path, inside double quotes. The returned path name is then kept by libcurl for subsequent uses.
Due to a flaw in the string parser for this directory name, a directory name passed like this but without a closing double quote would lead to libcurl not adding a trailing NUL byte to the buffer holding the name. When libcurl would then later access the string, it could read beyond the allocated heap buffer and crash or wrongly access data beyond the buffer, thinking it was part of the path.
A malicious server could abuse this fact and effectively prevent libcurl-based clients to work with it - the PWD command is always issued on new FTP connections and the mistake has a high chance of causing a segfault.
There is no limit on the password length.
A remote attacker may be able to cause an affected SSH server to use excessive amount of CPU by sending very long passwords, when PasswordAuthentication is enabled by the system administrator.
There is a programming error in the Heimdal implementation that used an unauthenticated, plain-text version of the KDC-REP service name found in a ticket.
An attacker who has control of the network between a client and the service it talks to will be able to impersonate the service, allowing a successful man-in-the-middle (MITM) attack that circumvents the mutual authentication.

sam2p developers report:
In sam2p 0.49.3, a heap-based buffer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp.
In sam2p 0.49.3, the in_xpm_reader function in in_xpm.cpp has an integer signedness error, leading to a crash when writing to an out-of-bounds array element.
In sam2p 0.49.3, an integer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp, leading to an invalid write operation.
In sam2p 0.49.3, the pcxLoadRaster function in in_pcx.cpp has an integer signedness error leading to a heap-based buffer overflow.
Because of an integer overflow in sam2p 0.49.3, a loop executes 0xffffffff times, ending with an invalid read of size 1 in the Image::Indexed::sortPal function in image.cpp. However, this also causes memory corruption because of an attempted write to the invalid d[0xfffffffe] array element.
In sam2p 0.49.3, there is an invalid read of size 2 in the parse_rgb function in in_xpm.cpp. However, this can also cause a write to an illegal address.
libraw developers report:
In LibRaw through 0.18.4, an out of bounds read flaw related to kodak_65000_load_raw has been reported in dcraw/dcraw.c and internal/dcraw_common.cpp. An attacker could possibly exploit this flaw to disclose potentially sensitive memory or cause an application crash.
Steffan Karger reports:
The bounds check in read_key() was performed after using the value, instead of before. If 'key-method 1' is used, this allowed an attacker to send a malformed packet to trigger a stack buffer overflow. [...]
Note that 'key-method 1' has been replaced by 'key method 2' as the default in OpenVPN 2.0 (released on 2005-04-17), and explicitly deprecated in 2.4 and marked for removal in 2.5. This should limit the amount of users impacted by this issue.

The Asterisk project reports:
This is a follow up advisory to AST-2017-005.
Insufficient RTCP packet validation could allow reading stale buffer contents and when combined with the "nat" and "symmetric_rtp" options allow redirecting where Asterisk sends the next RTCP report.
The RTP stream qualification to learn the source address of media always accepted the first RTP packet as the new source and allowed what AST-2017-005 was mitigating. The intent was to qualify a series of packets before accepting the new source address.
The RTP/RTCP stack will now validate RTCP packets before processing them.
Ruby blog:
CVE-2017-0898: Buffer underrun vulnerability in Kernel.sprintf
If a malicious format string which contains a precious specifier (*) is passed and a huge minus value is also passed to the specifier, buffer underrun may be caused. In such situation, the result may contains heap, or the Ruby interpreter may crash.
CVE-2017-10784: Escape sequence injection vulnerability in the Basic authentication of WEBrick
When using the Basic authentication of WEBrick, clients can pass an arbitrary string as the user name. WEBrick outputs the passed user name intact to its log, then an attacker can inject malicious escape sequences to the log and dangerous control characters may be executed on a victim’s terminal emulator.
This vulnerability is similar to a vulnerability already fixed, but it had not been fixed in the Basic authentication.
CVE-2017-14033: Buffer underrun vulnerability in OpenSSL ASN1 decode

The attacker access geminabox system and uploads the gem file (or uses CSRF/SSRF attack to do so).
From now on, any user access Geminabox web server, executes the malicious XSS payload, that will delete any gems on the server, and won't let users use the geminabox anymore. (make victim's browser crash or redirect them to other hosts).
The Fuzzing Project reports:
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.

A carefully crafted URI in a From, To or Contact header could cause Asterisk to crash.
The Asterisk project reports:
AST-2017-005 - A change was made to the strict RTP support in the RTP stack to better tolerate late media when a reinvite occurs. When combined with the symmetric RTP support this introduced an avenue where media could be hijacked. Instead of only learning a new address when expected the new code allowed a new source address to be learned at all times.
AST-2017-006 - The app_minivm module has an "externnotify" program configuration option that is executed by the MinivmNotify dialplan application. The application uses the caller-id name and number as part of a built string passed to the OS shell for interpretation and execution. Since the caller-id name and number can come from an untrusted source, a crafted caller-id name or number allows an arbitrary shell command injection.

mnaberez reports:
supervisord can be configured to run an HTTP server on a TCP socket and/or a Unix domain socket. The HTTP server is how supervisorctl communicates with supervisord. If an HTTP server has been enabled, it will always serve both HTML pages and an XML-RPC interface. A vulnerability has been found where an authenticated client can send a malicious XML-RPC request to supervisord that will run arbitrary shell commands on the server. The commands will be run as the same user as supervisord. Depending on how supervisord has been configured, this may be root.
This vulnerability can only be exploited by an authenticated client or if supervisord has been configured to run an HTTP server without authentication. If authentication has not been enabled, supervisord will log a message at the critical level every time it starts.

Mercurial Release Notes:
CVE-2017-1000115
Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository.
CVE-2017-1000116
Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed.
subversion team reports:
A Subversion client sometimes connects to URLs provided by the repository. This happens in two primary cases: during 'checkout', 'export', 'update', and 'switch', when the tree being downloaded contains svn:externals properties; and when using 'svnsync sync' with one URL argument.
A maliciously constructed svn+ssh:// URL would cause Subversion clients to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server.
The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.
An exploit has been tested.
GitLab reports:
Remote Command Execution in git client
An external code review performed by Recurity-Labs identified a remote command execution vulnerability in git that could be exploited via the "Repo by URL" import option in GitLab. The command line git client was not properly escaping command line arguments in URLs using the SSH protocol before invoking the SSH client. A specially crafted URL could be used to execute arbitrary shell commands on the GitLab server.
To fully patch this vulnerability two fixes were needed. The Omnibus versions of GitLab contain a patched git client. For source users who may still be running an older version of git, GitLab now also blocks import URLs containing invalid host and usernames.
This issue has been assigned CVE-2017-12426.Improper sanitization of GitLab export files on import
GitLab versions 8.13.3, 8.12.8, 8.11.10, 8.10.13, and 8.9.12 contained a patch for a critical directory traversal vulnerability in the GitLab export feature that could be exploited by including symlinks in the export file and then re-importing it to a GitLab instance. This vulnerability was patched by checking for and removing symlinks in these files on import.
Recurity-Labs also determined that this fix did not properly remove symlinks for hidden files. Though not as dangerous as the original vulnerability hidden file symlinks could still be used to steal copies of git repositories belonging to other users if the path to the git repository was known by the attacker. An updated fix has been included in these releases that properly removes all symlinks.
This import option was not made available to non-admin users until GitLab 8.13.0.

When under stress, closing many connections, the HTTP/2 handling code would sometimes access memory after it has been freed, resulting in potentially erratic behaviour.important: Uninitialized memory reflection in mod_auth_digest (CVE-2017-9788)
The value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments. by mod_auth_digest.
Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault.

The samba project reports:
A MITM attacker may impersonate a trusted server and thus gain elevated access to the domain by returning malicious replication or authorization data.
Updates are now available for all active Node.js release lines as well as the 7.x line. These include the fix for the high severity vulnerability identified in the initial announcement, one additional lower priority Node.js vulnerability in the 4.x release line, as well as some lower priority fixes for Node.js dependencies across the current release lines.
Constant Hashtable Seeds (CVE pending)
Node.js was susceptible to hash flooding remote DoS attacks as the HashTable seed was constant across a given released version of Node.js. This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup. Thanks to Jann Horn of Google Project Zero for reporting this vulnerability.
This is a high severity vulnerability and applies to all active release lines (4.x, 6.x, 8.x) as well as the 7.x line.
http.get with numeric authorization options creates uninitialized buffers
Application code that allows the auth field of the options object used with http.get() to be set to a number can result in an uninitialized buffer being created/used as the authentication string.
This is a low severity defect and only applies to the 4.x release line.

the PHP project reports:
- A stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer (CVE-2017-9224).
- A heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption (CVE-2017-9226).
- A stack out-of-bounds read occurs in mbc_enc_len() during regular expression searching. Invalid handling of reg->dmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer (CVE-2017-9227).
- A heap out-of-bounds write occurs in bitset_set_range() during regular expression compilation due to an uninitialized variable from an incorrect state transition. An incorrect state transition in parse_char_class() could create an execution path that leaves a critical local variable uninitialized until it's used as an index, resulting in an out-of-bounds write memory corruption (CVE-2017-9228).
- A SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition (CVE-2017-9228).

This may, in some cases, enable bypass of capath policy in Heimdal versions 1.5 through 7.2. Note, this may break sites that rely on the bug. With the bug some incomplete [capaths] worked, that should not have. These may now break authentication in some cross-realm configurations. (CVE-2017-6594)
ipfilter(4), capable of stateful packet inspection, using the "keep state" or "keep frags" rule options, will not only maintain the state of connections, such as TCP streams or UDP communication, it also maintains the state of fragmented packets. When a packet fragments are received they are cached in a hash table (and linked list). When a fragment is received it is compared with fragments already cached in the hash table for a match. If it does not match the new entry is used to create a new entry in the hash table. If on the other hand it does match, unfortunately the wrong entry is freed, the entry in the hash table. This results in use after free panic (and for a brief moment prior to the panic a memory leak due to the wrong entry being freed).
Carefully feeding fragments that are allowed to pass by an ipfilter(4) firewall can be used to cause a panic followed by reboot loop denial of service attack.

The Asterisk project reports:
A remote memory exhaustion can be triggered by sending an SCCP packet to Asterisk system with "chan_skinny" enabled that is larger than the length of the SCCP header but smaller than the packet length specified in the header. The loop that reads the rest of the packet doesn't detect that the call to read() returned end-of-file before the expected number of bytes and continues infinitely. The "partial data" message logging in that tight loop causes Asterisk to exhaust all available memory.
The Asterisk project reports:
A remote crash can be triggered by sending a SIP packet to Asterisk with a specially crafted CSeq header and a Via header with no branch parameter. The issue is that the PJSIP RFC 2543 transaction key generation algorithm does not allocate a large enough buffer. By overrunning the buffer, the memory allocation table becomes corrupted, leading to an eventual crash.
The multi-part body parser in PJSIP contains a logical error that can make certain multi-part body parts attempt to read memory from outside the allowed boundaries. A specially-crafted packet can trigger these invalid reads and potentially induce a crash.
This issues is in PJSIP, and so the issue can be fixed without performing an upgrade of Asterisk at all. However, we are releasing a new version of Asterisk with the bundled PJProject updated to include the fix.
If you are running Asterisk with chan_sip, this issue does not affect you.

GitLab reports:
Information Disclosure in Issue and Merge Request Trackers
During an internal code review a critical vulnerability in the GitLab Issue and Merge Request trackers was discovered. This vulnerability could allow a user with access to assign ownership of an issue or merge request to another user to disclose that user's private token, email token, email address, and encrypted OTP secret. Reporter-level access to a GitLab project is required to exploit this flaw.
SSRF when importing a project from a Repo by URL
GitLab instances that have enabled project imports using "Repo by URL" were vulnerable to Server-Side Request Forgery attacks. By specifying a project import URL of localhost an attacker could target services that are bound to the local interface of the server. These services often do not require authentication. Depending on the service an attacker might be able craft an attack using the project import request URL.
Links in Environments tab vulnerable to tabnabbing
edio via HackerOne reported that user-configured Environment links include target=_blank but do not also include rel: noopener noreferrer. Anyone clicking on these links may therefore be subjected to tabnabbing attacks where a link back to the requesting page is maintained and can be manipulated by the target server.
Accounts with email set to "Do not show on profile" have addresses exposed in public atom feed
Several GitLab users reported that even with "Do not show on profile" configured for their email addresses those addresses were still being leaked in Atom feeds if they commented on a public project.

Samuli Seppänen reports:
OpenVPN v2.4.0 was audited for security vulnerabilities independently by Quarkslabs (funded by OSTIF) and Cryptography Engineering (funded by Private Internet Access) between December 2016 and April 2017. The primary findings were two remote denial-of-service vulnerabilities. Fixes to them have been backported to v2.3.15.
An authenticated client can do the 'three way handshake' (P_HARD_RESET, P_HARD_RESET, P_CONTROL), where the P_CONTROL packet is the first that is allowed to carry payload. If that payload is too big, the OpenVPN server process will stop running due to an ASSERT() exception. That is also the reason why servers using tls-auth/tls-crypt are protected against this attack - the P_CONTROL packet is only accepted if it contains the session ID we specified, with a valid HMAC (challenge-response). (CVE-2017-7478)
An authenticated client can cause the server's the packet-id counter to roll over, which would lead the server process to hit an ASSERT() and stop running. To make the server hit the ASSERT(), the client must first cause the server to send it 2^32 packets (at least 196 GB).

cURL security advisory:
libcurl would attempt to resume a TLS session even if the client certificate had changed. That is unacceptable since a server by specification is allowed to skip the client certificate check on resume, and may instead use the old identity which was established by the previous certificate (or no certificate).
libcurl supports by default the use of TLS session id/ticket to resume previous TLS sessions to speed up subsequent TLS handshakes. They are used when for any reason an existing TLS connection couldn't be kept alive to make the next handshake faster.
This flaw is a regression and identical to CVE-2016-5419 reported on August 3rd 2016, but affecting a different version range.

ISC reports:
A query with a specific set of characteristics could cause a server using DNS64 to encounter an assertion failure and terminate.
An attacker could deliberately construct a query, enabling denial-of-service against a server if it was configured to use the DNS64 feature and other preconditions were met.
Mistaken assumptions about the ordering of records in the answer section of a response containing CNAME or DNAME resource records could lead to a situation in which named would exit with an assertion failure when processing a response in which records occurred in an unusual order.
named contains a feature which allows operators to issue commands to a running server by communicating with the server process over a control channel, using a utility program such as rndc.
A regression introduced in a recent feature change has created a situation under which some versions of named can be caused to exit with a REQUIRE assertion failure if they are sent a null command string.

The phpMyAdmin team reports:
Summary
Bypass $cfg['Servers'][$i]['AllowNoPassword']
Description
A vulnerability was discovered where the restrictions caused by $cfg['Servers'][$i]['AllowNoPassword'] = false are bypassed under certain PHP versions. This can allow the login of users who have no password set even if the administrator has set $cfg['Servers'][$i]['AllowNoPassword'] to false (which is also the default).
This behavior depends on the PHP version used (it seems PHP 5 is affected, while PHP 7.0 is not).
Severity
We consider this vulnerability to be of moderate severity.
Mitigation factor
Set a password for all users.

Simon G. Tatham reports:
Many versions of PuTTY prior to 0.68 have a heap-corrupting integer overflow bug in the ssh_agent_channel_data function which processes messages sent by remote SSH clients to a forwarded agent connection. [...]
This bug is only exploitable at all if you have enabled SSH agent forwarding, which is turned off by default. Moreover, an attacker able to exploit this bug would have to have already be able to connect to the Unix-domain socket representing the forwarded agent connection. Since any attacker with that capability would necessarily already be able to generate signatures with your agent's stored private keys, you should in normal circumstances be defended against this vulnerability by the same precautions you and your operating system were already taking to prevent untrusted people from accessing your SSH agent.

Janos Follath reports:
- If a malicious peer supplies a certificate with a specially crafted secp224k1 public key, then an attacker can cause the server or client to attempt to free block of memory held on stack. Depending on the platform, this could result in a Denial of Service (client crash) or potentially could be exploited to allow remote code execution with the same privileges as the host application.
- If the client and the server both support MD5 and the client can be tricked to authenticate to a malicious server, then the malicious server can impersonate the client. To launch this man in the middle attack, the adversary has to compute a chosen-prefix MD5 collision in real time. This is very expensive computationally, but can be practical. Depending on the platform, this could result in a Denial of Service (client crash) or potentially could be exploited to allow remote code execution with the same privileges as the host application.
- A bug in the logic of the parsing of a PEM encoded Certificate Revocation List in mbedtls_x509_crl_parse() can result in an infinite loop. In versions before 1.3.10 the same bug results in an infinite recursion stack overflow that usually crashes the application. Methods and means of acquiring the CRLs is not part of the TLS handshake and in the strict TLS setting this vulnerability cannot be triggered remotely. The vulnerability cannot be triggered unless the application explicitly calls mbedtls_x509_crl_parse() or mbedtls_x509_crl_parse_file()on a PEM formatted CRL of untrusted origin. In which case the vulnerability can be exploited to launch a denial of service attack against the application.

Albert Aastals Cid reports:
A directory traversal issue was found in KTNEF which can be exploited by tricking a user into opening a malicious winmail.dat file. The issue allows to write files with the permission of the user opening the winmail.dat file during extraction.
Albert Astals Cid reports:
Using a malicious PAC file, and then using exfiltration methods in the PAC function FindProxyForURL() enables the attacker to expose full https URLs.
This is a security issue since https URLs may contain sensitive information in the URL authentication part (user:password@host), and in the path and the query (e.g. access tokens).
This attack can be carried out remotely (over the LAN) since proxy settings allow "Detect Proxy Configuration Automatically". This setting uses WPAD to retrieve the PAC file, and an attacker who has access to the victim's LAN can interfere with the WPAD protocols (DHCP/DNS+HTTP) and inject his/her own malicious PAC instead of the legitimate one.
WordPress versions 4.7.2 and earlier are affected by six security issues.

ikiwiki reports:
The ikiwiki maintainers discovered further flaws similar to CVE-2016-9646 in the passwordauth plugin's use of CGI::FormBuilder, with a more serious impact:
An attacker who can log in to a site with a password can log in as a different and potentially more privileged user.
An attacker who can create a new account can set arbitrary fields in the user database for that account
Mitre reports:
ikiwiki 3.20161219 does not properly check if a revision changes the access permissions for a page on sites with the git and recentchanges plugins and the CGI interface enabled, which allows remote attackers to revert certain changes by leveraging permissions to change the page before the revision was made.
When CGI::FormBuilder->field("foo") is called in list context (and in particular in the arguments to a subroutine that takes named arguments), it can return zero or more values for foo from the CGI request, rather than the expected single value. This breaks the usual Perl parsing convention for named arguments, similar to CVE-2014-1572 in Bugzilla (which was caused by a similar API design issue in CGI.pm).

httpd: fix two buffer overflows in IcyMetaData length calculation
The cURL project reports:
SSL_VERIFYSTATUS ignored
curl and libcurl support "OCSP stapling", also known as the TLS Certificate Status Request extension (using the CURLOPT_SSL_VERIFYSTATUS option). When telling curl to use this feature, it uses that TLS extension to ask for a fresh proof of the server's certificate's validity. If the server doesn't support the extension, or fails to provide said proof, curl is expected to return an error.
Due to a coding mistake, the code that checks for a test success or failure, ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. Contrary to how it used to function and contrary to how this feature is documented to work.
This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality.
The Xen Project reports:

The Apache Groovy project reports:
When an application with Groovy on classpath uses standard Java serialization mechanisms, e.g. to communicate between servers or to store local data, it is possible for an attacker to bake a special serialized object that will execute code directly when deserialized. All applications which rely on serialization and do not isolate the code which deserializes objects are subject to this vulnerability. This is similar to CVE-2015-3253 but this exploit involves extra wrapping of objects and catching of exceptions which are now safe guarded against.

PHPMailer is prone to an local information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in launching further attacks.
ISC reports:
A malformed query response received by a recursive server in response to a query of RTYPE ANY could trigger an assertion failure while named is attempting to add the RRs in the query response to the cache.
Depending on the type of query and the EDNS options in the query they receive, DNSSEC-enabled authoritative servers are expected to include RRSIG and other RRsets in their responses to recursive servers. DNSSEC-validating servers will also make specific queries for DS and other RRsets. Whether DNSSEC-validating or not, an error in processing malformed query responses that contain DNSSEC-related RRsets that are inconsistent with other RRsets in the same query response can trigger an assertion failure. Although the combination of properties which triggers the assertion should not occur in normal traffic, it is potentially possible for the assertion to be triggered deliberately by an attacker sending a specially-constructed answer.
An unusually-formed answer containing a DS resource record could trigger an assertion failure. While the combination of properties which triggers the assertion should not occur in normal traffic, it is potentially possible for the assertion to be triggered deliberately by an attacker sending a specially-constructed answer having the required properties.
An error in handling certain queries can cause an assertion failure when a server is using the nxdomain-redirect feature to cover a zone for which it is also providing authoritative service. A vulnerable server could be intentionally stopped by an attacker if it was using a configuration that met the criteria for the vulnerability and if the attacker could cause it to accept a query that possessed the required attributes.
The ssh-agent(1) agent supports loading a PKCS#11 module from outside a trusted whitelist. An attacker can request loading of a PKCS#11 module across forwarded agent-socket. [CVE-2016-10009]
When privilege separation is disabled, forwarded Unix domain sockets would be created by sshd(8) with the privileges of 'root' instead of the authenticated user. [CVE-2016-10010]
A remote attacker who have control of a forwarded agent-socket on a remote system and have the ability to write files on the system running ssh-agent(1) agent can run arbitrary code under the same user credential. Because the attacker must already have some control on both systems, it is relatively hard to exploit this vulnerability in a practical attack. [CVE-2016-10009]
When privilege separation is disabled (on FreeBSD, privilege separation is enabled by default and has to be explicitly disabled), an authenticated attacker can potentially gain root privileges on systems running OpenSSH server. [CVE-2016-10010]
Cesar Pereida Garcia reports:
The signing function in crypto/ecdsa/ecdsa_ossl.c in certain OpenSSL versions and forks is vulnerable to timing attacks when signing with the standardized elliptic curve P-256 despite featuring constant-time curve operations and modular inversion. A software defect omits setting the BN_FLG_CONSTTIME flag for nonces, failing to take a secure code path in the BN_mod_inverse method and therefore resulting in a cache-timing attack vulnerability.
A malicious user with local access can recover ECDSA P-256 private keys.
