This release fixes the issues discovered since 2.0.18, containing multiple important stability and correctness related improvements, including a fix for a bug which allowed malformed DNS records to cause netsplits on a network.

NVD reports:

The ff_dwt_decode function in libavcodec/jpeg2000dwt.c in FFmpeg before 2.8.4 does not validate the number of decomposition levels before proceeding with Discrete Wavelet Transform decoding, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.

The ff_get_buffer function in libavcodec/utils.c in FFmpeg before 2.8.4 preserves width and height values after a failure, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted .mov file.

The Mozilla Project reports:

Security researcher Karthikeyan Bhargavan reported an issue in Network Security Services (NSS) where MD5 signatures in the server signature within the TLS 1.2 ServerKeyExchange message are still accepted. This is an issue since NSS has officially disallowed the accepting MD5 as a hash algorithm in signatures since 2011. This issues exposes NSS based clients such as Firefox to theoretical collision-based forgery attacks.

The phpMyAdmin development team reports:

By calling some scripts that are part of phpMyAdmin in an unexpected way, it is possible to trigger phpMyAdmin to display a PHP error message which contains the full path of the directory where phpMyAdmin is installed.

We consider these vulnerabilities to be non-critical.

This path disclosure is possible on servers where the recommended setting of the PHP configuration directive display_errors is set to on, which is against the recommendations given in the PHP manual for a production server.

Salvatore Bonaccorso reports:

Hanno Boeck discovered a stack-based buffer overflow in the dpkg-deb component of dpkg, the Debian package management system. This flaw could potentially lead to arbitrary code execution if a user or an automated system were tricked into processing a specially crafted Debian binary package (.deb) in the old style Debian binary package format.

Ruby developer reports:

There is an unsafe tainted string vulnerability in Fiddle and DL. This issue was originally reported and fixed with CVE-2009-5147 in DL, but reappeared after DL was reimplemented using Fiddle and libffi.

And, about DL, CVE-2009-5147 was fixed at Ruby 1.9.1, but not fixed at other branches, then rubies which bundled DL except Ruby 1.9.1 are still vulnerable.

Bugzilla Security Advisory

During the generation of a dependency graph, the code for the HTML image map is generated locally if a local dot installation is used. With escaped HTML characters in a bug summary, it is possible to inject unfiltered HTML code in the map file which the CreateImagemap function generates. This could be used for a cross-site scripting attack.

If an external HTML page contains a <script> element with its src attribute pointing to a buglist in CSV format, some web browsers incorrectly try to parse the CSV file as valid JavaScript code. As the buglist is generated based on the privileges of the user logged into Bugzilla, the external page could collect confidential data contained in the CSV file.

Adam Maris, Red Hat Product Security, reports:

Pierre Schweitzer reports:

Any client sending the command "/op *" in a query will cause the Quassel core to crash.

Libvit development team reports:

Various virStorageVol* API operate on user-supplied volume names by concatenating the volume name to the pool location. Note that the virStoragePoolListVolumes API, when used on a storage pool backed by a directory in a file system, will only list volumes immediately in that directory (there is no traversal into subdirectories). However, other APIs such as virStorageVolCreateXML were not checking if a potential volume name represented one of the volumes that could be returned by virStoragePoolListVolumes; because they were not rejecting the use of '/' in a volume name.

Because no checking was done on volume names, a user could supply a potential volume name of something like '../../../etc/passwd' to attempt to access a file not belonging to the storage pool. When fine-grained Access Control Lists (ACL) are in effect, a user with storage_vol:create ACL permission but lacking domain:write permission could thus abuse virStorageVolCreateXML and similar APIs to gain access to files not normally permitted to that user. Fortunately, it appears that the only APIs that could leak information or corrupt files require read-write connection to libvirtd; and when ACLs are not in use (the default without any further configuration), a user with read-write access can already be considered to have full access to the machine, and without an escalation of privilege there is no security problem.

Jenkins Security Advisory:

Description

SECURITY-95 / CVE-2015-7536 (Stored XSS vulnerability through workspace files and archived artifacts)

In certain configurations, low privilege users were able to create e.g. HTML files in workspaces and archived artifacts that could result in XSS when accessed by other users. Jenkins now sends Content-Security-Policy headers that enables sandboxing and prohibits script execution by default.

SECURITY-225 / CVE-2015-7537 (CSRF vulnerability in some administrative actions)

Several administration/configuration related URLs could be accessed using GET, which allowed attackers to circumvent CSRF protection.

SECURITY-233 / CVE-2015-7538 (CSRF protection ineffective)

Malicious users were able to circumvent CSRF protection on any URL by sending specially crafted POST requests.

SECURITY-234 / CVE-2015-7539 (Jenkins plugin manager vulnerable to MITM attacks)

While the Jenkins update site data is digitally signed, and the signature verified by Jenkins, Jenkins did not verify the provided SHA-1 checksums for the plugin files referenced in the update site data. This enabled MITM attacks on the plugin manager, resulting in installation of attacker-provided plugins.

Daniel Knoppel reports:

It was discovered by the SUSE security team that it was possible, in some cases, for clients to overwrite headers set by the server, resulting in a medium level security issue. CVE-2015-7519 has been assigned to this issue.

Affected use-cases:

Header overwriting may occur if all of the following conditions are met:

• Apache integration mode, or standalone+builtin engine without a filtering proxy
• Ruby or Python applications only (Passenger 5); or any application (Passenger 4)
• The app depends on a request header containing a dash (-)
• The header is supposed to be trusted (set by the server)
• The client correctly guesses the header name

This vulnerability has been fixed by filtering out client headers that do not consist of alphanumeric/dash characters (Nginx already did this, so Passenger+Nginx was not affected). If your application depends on headers that don't conform to this, you can add a workaround in Apache specifically for those to convert them to a dash-based format.

NVD reports:

The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1, as used in Google Chrome before 46.0.2490.71 and other products, relies on a coefficient-partition count during multi-threaded operation, which allows remote attackers to cause a denial of service (race condition and memory corruption) or possibly have unspecified other impact via a crafted WebM file.

The ljpeg_decode_yuv_scan function in libavcodec/mjpegdec.c in FFmpeg before 2.8.2 omits certain width and height checks, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted MJPEG data.

The ff_hevc_parse_sps function in libavcodec/hevc_ps.c in FFmpeg before 2.8.2 does not validate the Chroma Format Indicator, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted High Efficiency Video Coding (HEVC) data.

The decode_uncompressed function in libavcodec/faxcompr.c in FFmpeg before 2.8.2 does not validate uncompressed runs, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted CCITT FAX data.

The init_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.8.2 does not enforce minimum-value and maximum-value constraints on tile coordinates, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.

The jpeg2000_read_main_headers function in libavcodec/jpeg2000dec.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not enforce uniqueness of the SIZ marker in a JPEG 2000 image, which allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via a crafted image with two or more of these markers.

Integer overflow in the ff_ivi_init_planes function in libavcodec/ivi.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via crafted image dimensions in Indeo Video Interactive data.

The smka_decode_frame function in libavcodec/smacker.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not verify that the data size is consistent with the number of channels, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Smacker data.

The Xen Project reports:

A malicious HVM guest administrator can cause a denial of service. Specifically, prevent use of a physical CPU for a significant, perhaps indefinite period. If a host watchdog (Xen or dom0) is in use, this can lead to a watchdog timeout and consequently a reboot of the host. If another, innocent, guest, is configured with a watchdog, this issue can lead to a reboot of such a guest.

libpng reports:

CVE for a vulnerability in libpng, all versions, in the png_set_PLTE/png_get_PLTE functions. These functions failed to check for an out-of-range palette when reading or writing PNG files with a bit_depth less than 8. Some applications might read the bit depth from the IHDR chunk and allocate memory for a 2^N entry palette, while libpng can return a palette with up to 256 entries even when the bit depth is less than 8.

Jenkins Developers report:

Unsafe deserialization allows unauthenticated remote attackers to run arbitrary code on the Jenkins master.

owncloud.org reports:

The ownCloud Desktop Client was vulnerable against MITM attacks until version 2.0.0 in combination with self-signed certificates.

The Xen Project reports:

Guests configured with PoD might be unstable, especially under load. In an affected guest, an unprivileged guest user might be able to cause a guest crash, perhaps simply by applying load so as to cause heavy memory pressure within the guest.

The Xen Project reports:

HYPERCALL_xenoprof_op and HYPERVISOR_xenpmu_op log some errors and attempts at invalid operations. These log messages are not rate-limited, even though they can be triggered by guests.

A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack.

The Xen Project reports:

A domain's xenoprofile state contains an array of per-vcpu information... This array is leaked on domain teardown. This memory leak could -- over time -- exhaust the host's memory.

The following parties can mount a denial of service attack affecting the whole system:

• A malicious guest administrator via XENOPROF_get_buffer.
• A domain given suitable privilege over another domain via XENOPROF_set_passive (this would usually be a domain being used to profile another domain, eg with the xenoprof tool).

The ability to also restart or create suitable domains is also required to fully exploit the issue. Without this the leak is limited to a small multiple of the maximum number of vcpus for the domain.

The Xen Project reports:

When running an HVM domain in Populate-on-Demand mode, Xen would sometimes search the domain for memory to reclaim, in response to demands for population of other pages in the same domain. This search runs without preemption. The guest can, by suitable arrangement of its memory contents, create a situation where this search is a time-consuming linear scan of the guest's address space.

A malicious HVM guest administrator can cause a denial of service. Specifically, prevent use of a physical CPU for a significant period.

The Xen Project reports:

A domain's primary array of vcpu pointers can be allocated by a toolstack exactly once in the lifetime of a domain via the XEN_DOMCTL_max_vcpus hypercall. This array is leaked on domain teardown. This memory leak could -- over time -- exhaust the host's memory.

A domain given partial management control via XEN_DOMCTL_max_vcpus can mount a denial of service attack affecting the whole system. The ability to also restart or create suitable domains is also required to fully exploit the issue. Without this the leak is limited to a small multiple of the maximum number of vcpus for the domain. The maximum leak is 64kbytes per domain (re)boot (less on ARM).

The Xen Project reports:

The code to validate level 2 page table entries is bypassed when certain conditions are satisfied. This means that a PV guest can create writable mappings using super page mappings. Such writable mappings can violate Xen intended invariants for pages which Xen is supposed to keep read-only. This is possible even if the "allowsuperpage" command line option is not used.

Malicious PV guest administrators can escalate privilege so as to control the whole system.

The Xen Project reports:

Callers of libxl can specify that a disk should be read-only to the guest. However, there is no code in libxl to pass this information to qemu-xen (the upstream-based qemu); and indeed there is no way in qemu to make a disk read-only.

The vulnerability is exploitable only via devices emulated by the device model, not the parallel PV devices for supporting PVHVM. Normally the PVHVM device unplug protocol renders the emulated devices inaccessible early in boot.

Malicious guest administrators or (in some situations) users may be able to write to supposedly read-only disk images.

CDROM devices (that is, devices specified to be presented to the guest as CDROMs, regardless of the nature of the backing storage on the host) are not affected.

MITRE reports:

Cross-site scripting (XSS) vulnerability in the HTML-Scrubber module before 0.15 for Perl, when the comment feature is enabled, allows remote attackers to inject arbitrary web script or HTML via a crafted comment.

The Mozilla Project reports:

Security researcher Khalil Zhani reported that a maliciously crafted vp9 format video could be used to trigger a buffer overflow while parsing the file. This leads to a potentially exploitable crash due to a flaw in the libvpx library.

PowerDNS reports:

A bug was found using afl-fuzz in our packet parsing code. This bug, when exploited, causes an assertion error and consequent termination of the the pdns_server process, causing a Denial of Service.

Ben Harris reports:

Versions of PuTTY and pterm between 0.54 and 0.65 inclusive have a potentially memory-corrupting integer overflow in the handling of the ECH (erase characters) control sequence in the terminal emulator.

To exploit a vulnerability in the terminal emulator, an attacker must be able to insert a carefully crafted escape sequence into the terminal stream. For a PuTTY SSH session, this must be before encryption, so the attacker likely needs access to the server you're connecting to. For instance, an attacker on a multi-user machine that you connect to could trick you into running cat on a file they control containing a malicious escape sequence. (Unix write(1) is not a vector for this, if implemented correctly.)

Only PuTTY, PuTTYtel, and pterm are affected; other PuTTY tools do not include the terminal emulator, so cannot be exploited this way.

The Apache OpenOffice Project reports:

A vulnerability in OpenOffice settings of OpenDocument Format files and templates allows silent access to files that are readable from an user account, over-riding the user's default configuration settings. Once these files are imported into a maliciously-crafted document, the data can be silently hidden in the document and possibly exported to an external party without being observed.

The Apache OpenOffice Project reports:

A crafted ODF document can be used to create a buffer that is too small for the amount of data loaded into it, allowing an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.

The Apache OpenOffice Project reports:

A crafted Microsoft Word DOC file can be used to specify a document buffer that is too small for the amount of data provided for it. Failure to detect the discrepancy allows an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.

The Apache OpenOffice Project reports:

A crafted Microsoft Word DOC can contain invalid bookmark positions leading to memory corruption when the document is loaded or bookmarks are manipulated. The defect allows an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.

The CodeIgniter changelog reports:

Fixed an XSS attack vector in Security Library method xss_clean().

Changed Config Library method base_url() to fallback to ``$_SERVER['SERVER_ADDR']`` in order to avoid Host header injections.

Changed CAPTCHA Helper to try to use the operating system's PRNG first.

The OpenAFS development team reports:

When constructing an Rx acknowledgment (ACK) packet, Andrew-derived Rx implementations do not initialize three octets of data that are padding in the C language structure and were inadvertently included in the wire protocol (CVE-2015-7762). Additionally, OpenAFS Rx in versions 1.5.75 through 1.5.78, 1.6.0 through 1.6.14, and 1.7.0 through 1.7.32 include a variable-length padding at the end of the ACK packet, in an attempt to detect the path MTU, but only four octets of the additional padding are initialized (CVE-2015-7763).

RedHat bugzilla reports:

In dual screen configurations, unplugging one screen will cause xscreensaver to crash, leaving the screen unlocked.

The lldpd developer Vincent Bernat reports:

A buffer overflow may allow arbitrary code execution only if hardening was disabled.

Malformed packets should not make lldpd crash. Ensure we can handle them by not using assert() in this part.

Wireshark development team reports:

Drupal development team reports:

The Overlay module in Drupal core displays administrative pages as a layer over the current page (using JavaScript), rather than replacing the page in the browser window. The Overlay module does not sufficiently validate URLs prior to displaying their contents, leading to an open redirect vulnerability.

This vulnerability is mitigated by the fact that it can only be used against site users who have the "Access the administrative overlay" permission, and that the Overlay module must be enabled.

An incomplete fix for this issue was released as part of SA-CORE-2015-002.

The phpMyAdmin development team reports:

This vulnerability allows an attacker to perform a content spoofing attack using the phpMyAdmin's redirection mechanism to external sites.

We consider this vulnerability to be non critical since the spoofed content is escaped and no HTML injection is possible.

MediaWiki reports:

Wikipedia user RobinHood70 reported two issues in the chunked upload API. The API failed to correctly stop adding new chunks to the upload when the reported size was exceeded (T91203), allowing a malicious users to upload add an infinite number of chunks for a single file upload. Additionally, a malicious user could upload chunks of 1 byte for very large files, potentially creating a very large number of files on the server's filesystem (T91205).

Internal review discovered that it is not possible to throttle file uploads.

Internal review discovered a missing authorization check when removing suppression from a revision. This allowed users with the 'viewsuppressed' user right but not the appropriate 'suppressrevision' user right to unsuppress revisions.

Richard Stanway from teamliquid.net reported that thumbnails of PNG files generated with ImageMagick contained the local file path in the image metadata.

ntp.org reports:

Git release notes:

Some protocols (like git-remote-ext) can execute arbitrary code found in the URL. The URLs that submodules use may come from arbitrary sources (e.g., .gitmodules files in a remote repository), and can hurt those who blindly enable recursive fetch. Restrict the allowed protocols to well known and safe ones.

Salt release notes:

CVE-2015-6918 - Git modules leaking HTTPS auth credentials to debug log

Updated the Git state and execution modules to no longer display HTTPS basic authentication credentials in loglevel debug output on the Salt master. These credentials are now replaced with REDACTED in the debug output. Thanks to Andreas Stieger for bringing this to our attention.

CVE-2015-6941 - win_useradd module and salt-cloud display passwords in debug log

Updated the win_useradd module return data to no longer include the password of the newly created user. The password is now replaced with the string XXX-REDACTED-XXX. Updated the Salt Cloud debug output to no longer display win_password and sudo_password authentication credentials. Also updated the Linode driver to no longer display authentication credentials in debug logs. These credentials are now replaced with REDACTED in the debug output.

Firefox Developers report:

Security researcher Abdulrahman Alqabandi reported that the fetch() API did not correctly implement the Cross-Origin Resource Sharing (CORS) specification, allowing a malicious page to access private data from other origins. Mozilla developer Ben Kelly independently reported the same issue.

Adobe reports:

These updates resolve type confusion vulnerabilities that could lead to code execution (CVE-2015-7645, CVE-2015-7647, CVE-2015-7648).

Qualys reports:

During the code review of OpenSMTPD a memory leak and buffer overflow (an off-by-one, usually stack-based) were discovered in LibreSSL's OBJ_obj2txt() function. This function is called automatically during a TLS handshake (both client-side, unless an anonymous mode is used, and server-side, if client authentication is requested).

ARM Limited reports:

When the client creates its ClientHello message, due to insufficient bounds checking it can overflow the heap-based buffer containing the message while writing some extensions. Two extensions in particular could be used by a remote attacker to trigger the overflow: the session ticket extension and the server name indication (SNI) extension.

Magento, Inc. reports:

Matthijs Kooijman reports:

It seems that the whiptail, cdialog and kdialog backends apply some improper escaping in their shell commands, causing special characters present in menu item titles to be interpreted by the shell. This includes the backtick evaluation operator, so this constitutes a security issue, allowing execution of arbitrary commands if an attacker has control over the text displayed in a menu.

Matthias Bussonnier reports:

Summary: Local folder name was used in HTML templates without escaping, allowing XSS in said pages by carefully crafting folder name and URL to access it.

URI with issues:

• GET /tree/**

Benjamin RK reports:

Vulnerability: A maliciously forged file opened for editing can execute javascript, specifically by being redirected to /files/ due to a failure to treat the file as plain text.

URI with issues:

• GET /edit/**

PostgreSQL project reports:

Two security issues have been fixed in this release which affect users of specific PostgreSQL features.

• CVE-2015-5289 json or jsonb input values constructed from arbitrary user input can crash the PostgreSQL server and cause a denial of service.
• CVE-2015-5288: The crypt() function included with the optional pgCrypto extension could be exploited to read a few additional bytes of memory. No working exploit for this issue has been developed.

Zend Framework developers report:

The PDO adapters of Zend Framework 1 do not filter null bytes values in SQL statements. A PDO adapter can treat null bytes in a query as a string terminator, allowing an attacker to add arbitrary SQL following a null byte, and thus create a SQL injection.

OpenSMTPD developers report:

fix an mda buffer truncation bug which allows a user to create forward files that pass session checks but fail delivery later down the chain, within the user mda

fix remote buffer overflow in unprivileged pony process

reworked offline enqueue to better protect against hardlink attacks

ARM Limited reports:

Florian Weimar from Red Hat published on Lenstra's RSA-CRT attach for PKCS#1 v1.5 signatures. These releases include countermeasures against that attack.

Fabian Foerg of Gotham Digital Science found a possible client-side NULL pointer dereference, using the AFL Fuzzer. This dereference can only occur when misusing the API, although a fix has still been implemented.

ARM Limited reports:

In order to strengthen the minimum requirements for connections and to protect against the Logjam attack, the minimum size of Diffie-Hellman parameters accepted by the client has been increased to 1024 bits.

In addition the default size for the Diffie-Hellman parameters on the server are increased to 2048 bits. This can be changed with ssl_set_dh_params() in case this is necessary.

We found a heap overflow and a DoS in the gdk-pixbuf implementation triggered by the scaling of tga file.

We found a heap overflow in the gdk-pixbuf implementation triggered by the scaling of gif file.

Plone.org reports:

Versions Affected: All current Plone versions.

Versions Not Affected: None.

Nature of vulnerability: Allows creation of members by anonymous users on sites that have self-registration enabled, allowing bypass of CAPTCHA and similar protections against scripted attacks.

The patch can be added to buildouts as Products.PloneHotfix20150910 (available from PyPI) or downloaded from Plone.org.

Immediate Measures You Should Take: Disable self-registration until you have applied the patch.

Plone's URL checking infrastructure includes a method for checking if URLs valid and located in the Plone site. By passing HTML into this specially crafted url, XSS can be achieved.

OpenSMTPD developers report:

an oversight in the portable version of fgetln() that allows attackers to read and write out-of-bounds memory

multiple denial-of-service vulnerabilities that allow local users to kill or hang OpenSMTPD

a stack-based buffer overflow that allows local users to crash OpenSMTPD, or execute arbitrary code as the non-chrooted _smtpd user

a hardlink attack (or race-conditioned symlink attack) that allows local users to unset the chflags() of arbitrary files

a hardlink attack that allows local users to read the first line of arbitrary files (for example, root's hash from /etc/master.passwd)

a denial-of-service vulnerability that allows remote attackers to fill OpenSMTPD's queue or mailbox hard-disk partition

an out-of-bounds memory read that allows remote attackers to crash OpenSMTPD, or leak information and defeat the ASLR protection

a use-after-free vulnerability that allows remote attackers to crash OpenSMTPD, or execute arbitrary code as the non-chrooted _smtpd user

The Apache James Project reports:

This release has many enhancements and bug fixes over the previous release. See the Release Notes for a detailed list of changes. Some of the earlier defects could turn a James mail server into an Open Relay and allow files to be written on disk. All users of James Server are urged to upgrade to version v2.3.2.1 as soon as possible.

The OTRS project reports:

An attacker with valid LOCAL credentials could access and manipulate the process ID file for bin/otrs.schduler.pl from the CLI.

The Proc::Daemon module 0.14 for Perl uses world-writable permissions for a file that stores a process ID, which allows local users to have an unspecified impact by modifying this file.

Security: The Session Library now uses HMAC authentication instead of a simple MD5 checksum.

The CodeIgniter changelog reports:

An improvement was made to the MySQL and MySQLi drivers to prevent exposing a potential vector for SQL injection on sites using multi-byte character sets in the database client connection.

An incompatibility in PHP versions < 5.2.3 and MySQL > 5.0.7 with mysql_set_charset() creates a situation where using multi-byte character sets on these environments may potentially expose a SQL injection attack vector. Latin-1, UTF-8, and other "low ASCII" character sets are unaffected on all environments.

If you are running or considering running a multi-byte character set for your database connection, please pay close attention to the server environment you are deploying on to ensure you are not vulnerable.

Amos Jeffries, release manager of the Squid-3 series, reports:

Vulnerable versions are 3.5.0.1 to 3.5.8 (inclusive), which are built with OpenSSL and configured for "SSL-Bump" decryption.

Integer overflows can lead to invalid pointer math reading from random memory on some CPU architectures. In the best case this leads to wrong TLS extensions being used for the client, worst-case a crash of the proxy terminating all active transactions.

Incorrect message size checks and assumptions about the existence of TLS extensions in the SSL/TLS handshake message can lead to very high CPU consumption (up to and including 'infinite loop' behaviour).

The above can be triggered remotely. Though there is one layer of authorization applied before this processing to check that the client is allowed to use the proxy, that check is generally weak. MS Skype on Windows XP is known to trigger some of these.

The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.

Bugzilla Security Advisory

Login names (usually an email address) longer than 127 characters are silently truncated in MySQL which could cause the domain name of the email address to be corrupted. An attacker could use this vulnerability to create an account with an email address different from the one originally requested. The login name could then be automatically added to groups based on the group's regular expression setting.

The Mozilla Project reports:

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative the possibility of memory corruption during the decoding of Ogg Vorbis files. This can cause a crash during decoding and has the potential for remote code execution.

The RedHat Project reports:

Will Drewry of the Google Security Team reported multiple issues in OGG Vorbis and Tremor libraries, that could cause application using those libraries to crash (NULL pointer dereference or divide by zero), enter an infinite loop or cause heap overflow caused by integer overflow.

Guanxing Wen reports:

PCRE library is prone to a vulnerability which leads to Heap Overflow. During the compilation of a malformed regular expression, more data is written on the malloced block than the expected size output by compile_regex(). The Heap Overflow vulnerability is caused by the following regular expression.

/(?J:(?|(:(?|(?'R')(\z(?|(?'R')(\k'R')|((?'R')))k'R')|((?'R')))H'Ak'Rf)|s(?'R')))/

A dry run of this particular regular expression with pcretest will reports "double free or corruption (!prev)". But it is actually a heap overflow problem. The overflow only affects pcre 8.x branch, pcre2 branch is not affected.

Drupal development team reports:

This security advisory fixes multiple vulnerabilities. See below for a list.

Cross-site Scripting - Ajax system - Drupal 7

A vulnerability was found that allows a malicious user to perform a cross-site scripting attack by invoking Drupal.ajax() on a whitelisted HTML element.

This vulnerability is mitigated on sites that do not allow untrusted users to enter HTML.

Cross-site Scripting - Autocomplete system - Drupal 6 and 7

A cross-site scripting vulnerability was found in the autocomplete functionality of forms. The requested URL is not sufficiently sanitized.

This vulnerability is mitigated by the fact that the malicious user must be allowed to upload files.

SQL Injection - Database API - Drupal 7

A vulnerability was found in the SQL comment filtering system which could allow a user with elevated permissions to inject malicious code in SQL comments.

This vulnerability is mitigated by the fact that only one contributed module that the security team found uses the comment filtering system in a way that would trigger the vulnerability. That module requires you to have a very high level of access in order to perform the attack.

Cross-site Request Forgery - Form API - Drupal 6 and 7

A vulnerability was discovered in Drupal's form API that could allow file upload value callbacks to run with untrusted input, due to form token validation not being performed early enough. This vulnerability could allow a malicious user to upload files to the site under another user's account.

This vulnerability is mitigated by the fact that the uploaded files would be temporary, and Drupal normally deletes temporary files automatically after 6 hours.

Information Disclosure in Menu Links - Access system - Drupal 6 and 7

Users without the "access content" permission can see the titles of nodes that they do not have access to, if the nodes are added to a menu on the site that the users have access to.

OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world-writable. Local attackers may be able to write arbitrary messages to logged-in users, including terminal escape sequences. Reported by Nikolay Edigaryev.

Fixed a privilege separation weakness related to PAM support. Attackers who could successfully compromise the pre-authentication process for remote code execution and who had valid credentials on the host could impersonate other users.

Fixed a use-after-free bug related to PAM support that was reachable by attackers who could compromise the pre-authentication process for remote code execution.

OpenSSH 7.0 contained a logic error in PermitRootLogin= prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication. This problem was reported by Mantas Mikulenas.

Colin Percival reports:

1. SECURITY FIX: When constructing paths of objects being archived, a buffer could overflow by one byte upon encountering 1024, 2048, 4096, etc. byte paths. Theoretically this could be exploited by an unprivileged user whose files are being archived; I do not believe it is exploitable in practice, but I am offering a $1000 bounty for the first person who can prove me wrong: http://www.daemonology.net/blog/2015-08-21-tarsnap-1000-exploit-bounty.html

2. SECURITY FIX: An attacker with a machine's write keys, or with read keys and control of the tarsnap service, could make tarsnap allocate a large amount of memory upon listing archives or reading an archive the attacker created; on 32-bit machines, tarsnap can be caused to crash under the aforementioned conditions.

oCERT reports:

The stable VLC version suffers from an arbitrary pointer dereference vulnerability.

The vulnerability affects the 3GP file format parser, insufficient restrictions on a writable buffer can be exploited to execute arbitrary code via the heap memory. A specific 3GP file can be crafted to trigger the vulnerability.

Credit: vulnerability reported by Loren Maggiore of Trail of Bits.

Pengsu Cheng reports:

An use-after-free issue in Decoder.cpp was reported to upstream. The problem is due to lack of validation of ColorTableSize.

Gustavo Grieco reports:

We found a heap overflow and a DoS in the gdk-pixbuf implementation triggered by the scaling of a malformed bmp.

Tim Graham reports:

Denial-of-service possibility in logout() view by filling session store

Previously, a session could be created when anonymously accessing the django.contrib.auth.views.logout view (provided it wasn't decorated with django.contrib.auth.decorators.login_required as done in the admin). This could allow an attacker to easily create many new session records by sending repeated requests, potentially filling up the session store or causing other users' session records to be evicted.

The django.contrib.sessions.middleware.SessionMiddleware has been modified to no longer create empty session records.

This portion of the fix has been assigned CVE-2015-5963.

Additionally, on the 1.4 and 1.7 series only, the contrib.sessions.backends.base.SessionBase.flush() and cache_db.SessionStore.flush() methods have been modified to avoid creating a new empty session. Maintainers of third-party session backends should check if the same vulnerability is present in their backend and correct it if so.

This portion of the fix has been assigned CVE-2015-5964. Anyone reporting a similar vulnerability in a third-party session backend should not use this CVE ID.

Thanks Lin Hua Cheng for reporting the issue.

Unreal reports:

Summary: If SASL support is enabled in UnrealIRCd (this is not the default) and is also enabled in your services package then a malicious user with a services account can cause UnrealIRCd to crash.

Martin Prpic reports:

A double free flaw was found in the way JasPer's jasper_image_stop_load() function parsed certain JPEG 2000 image files. A specially crafted file could cause an application using JasPer to crash.

Feist Josselin reports:

A new use-after-free was found in Jasper JPEG-200. The use-after-free appears in the function mif_process_cmpt of the src/libjasper/mif/mif_cod.c file.

Stefan Cornelius reports:

There's an integer overflow in the allocate_cells() function when trying to allocate the memory for worksheet with specially crafted row/column dimensions. This can be exploited to cause a heap memory corruption. The most likely outcome of this is a crash when trying to initialize the cells later in the function.

Jodie Cunningham reports:

#1: A flaw was found in the way FreeXL reads sectors from the input file. A specially crafted file could possibly result in stack corruption near freexl.c:3752.

#2: A flaw was found in the function allocate_cells(). A specially crafted file with invalid workbook dimensions could possibly result in stack corruption near freexl.c:1074

#3: A flaw was found in the way FreeXL handles a premature EOF. A specially crafted input file could possibly result in stack corruption near freexl.c:1131

#4: FreeXL 1.0.0g did not properly check requests for workbook memory allocation. A specially crafted input file could cause a Denial of Service, or possibly write onto the stack.

NIST reports:

Apache Tomcat Connectors (mod_jk) before 1.2.41 ignores JkUnmount rules for subtrees of previous JkMount rules, which allows remote attackers to access otherwise restricted artifacts via unspecified vectors.

The Xen Project reports:

The QEMU model of the RTL8139 network card did not sufficiently validate inputs in the C+ mode offload emulation. This results in uninitialized memory from the QEMU process's heap being leaked to the domain as well as to the network.

A guest may be able to read sensitive host-level data relating to itself which resides in the QEMU process.

Such information may include things such as information relating to real devices backing emulated devices or passwords which the host administrator does not intend to share with the guest admin.

The Xen Project reports:

When unplugging an emulated block device the device was not fully unplugged, meaning a second unplug attempt would attempt to unplug the device a second time using a previously freed pointer.

An HVM guest which has access to an emulated IDE disk device may be able to exploit this vulnerability in order to take over the qemu process elevating its privilege to that of the qemu process.

The PHP project reports:

MediaWiki reports:

Internal review discovered that Special:DeletedContributions did not properly protect the IP of autoblocked users. This fix makes the functionality of Special:DeletedContributions consistent with Special:Contributions and Special:BlockList.

Internal review discovered that watchlist anti-csrf tokens were not being compared in constant time, which could allow various timing attacks. This could allow an attacker to modify a user's watchlist via csrf

John Menerick reported that MediaWiki's thumb.php failed to sanitize various error messages, resulting in xss.

Jouni Malinen reports:

The EAP-PWD module performed insufficient validation on packets received from an EAP peer. This module is not enabled in the default configuration. Administrators must manually enable it for their server to be vulnerable. Only versions 3.0 up to 3.0.8 are affected.

gnutls.org reports:

Kurt Roeckx reported that decoding a specific certificate with very long DistinguishedName (DN) entries leads to double free, which may result to a denial of service. Since the DN decoding occurs in almost all applications using certificates it is recommended to upgrade the latest GnuTLS version fixing the issue. Recommendation: Upgrade to GnuTLS 3.4.4, or 3.3.17.

Karthikeyan Bhargavan reports:

GnuTLS does not by default support MD5 signatures. Indeed the RSA-MD5 signature-hash algorithm needs to be explicitly enabled using the priority option VERIFY_ALLOW_SIGN_RSA_MD5. In the NORMAL and SECURE profiles, GnuTLS clients do not offer RSA-MD5 in the signature algorithms extension. However, we find that all GnuTLS clients still accept RSA-MD5 in the ServerKeyExchange and GnuTLS servers still accept RSA-MD5 in the ClientCertificateVerify.

oss-security-list@demlak.de reports:

An unauthenticated remote attacker is able to get the database password via webaccess due to wrong file permissions of the /logs/ folder in froxlor version 0.9.33.1 and earlier. The plain SQL password and username may be stored in the /logs/sql-error.log file. This directory is publicly reachable under the default configuration/setup.

Note that froxlor 0.9.33.2 prevents future logging of passwords but does not retroactively remove passwords already logged. Michael Kaufmann, the Froxlor lead developer reports:

Removing all .log files from the directory should do the job, alternatively just use the class.ConfigIO.php from Github

Best Practical reports:

RT 4.0.0 and above are vulnerable to a cross-site scripting (XSS) attack via the user and group rights management pages. This vulnerability is assigned CVE-2015-5475. It was discovered and reported by Marcin Kopec at Data Reliance Shared Service Center.

RT 4.2.0 and above are vulnerable to a cross-site scripting (XSS) attack via the cryptography interface. This vulnerability could allow an attacker with a carefully-crafted key to inject JavaScript into RT's user interface. Installations which use neither GnuPG nor S/MIME are unaffected.

Brian Warner reports:

The "flappserver" feature was found to have a vulnerability in the service-lookup code which, when combined with an attacker who has the ability to write files to a location where the flappserver process could read them, would allow that attacker to obtain control of the flappserver process.

The Mozilla Project reports:

Using the Address Sanitizer tool, security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team found an out-of-bounds write when buffering WebM format video containing frames with invalid tile sizes. This can lead to a potentially exploitable crash during WebM video playback.

Adobe reports:

Adobe has released security updates for Adobe Flash Player. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.

Shibboleth consortium reports:

Shibboleth SP software crashes on well-formed but invalid XML.

The Service Provider software contains a code path with an uncaught exception that can be triggered by an unauthenticated attacker by supplying well-formed but schema-invalid XML in the form of SAML metadata or SAML protocol messages. The result is a crash and so causes a denial of service.

You must rebuild opensaml and shibboleth with xmltooling-1.5.5 or later. The easiest way to do so is to update the whole chain including shibboleth-2.5.5 an opensaml2.5.5.

oCERT reports:

The FreeRADIUS server relies on OpenSSL to perform certificate validation, including Certificate Revocation List (CRL) checks. The FreeRADIUS usage of OpenSSL, in CRL application, limits the checks to leaf certificates, therefore not detecting revocation of intermediate CA certificates.

An unexpired client certificate, issued by an intermediate CA with a revoked certificate, is therefore accepted by FreeRADIUS.

Specifically sets the X509_V_FLAG_CRL_CHECK flag for leaf certificate CRL checks, but does not use X509_V_FLAG_CRL_CHECK_ALL for CRL checks on the complete trust chain.

The FreeRADIUS project advises that the recommended configuration is to use self-signed CAs for all EAP-TLS methods.

The Xen Project reports:

The xl command line utility mishandles long configuration values when passed as command line arguments, with a buffer overrun.

A semi-trusted guest administrator or controller, who is intended to be able to partially control the configuration settings for a domain, can escalate their privileges to that of the whole host.

The Xen Project reports:

A buggy loop in Xen's compat_iret() function iterates the wrong way around a 32-bit index. Any 32-bit PV guest kernel can trigger this vulnerability by attempting a hypercall_iret with EFLAGS.VM set.

Given the use of __get/put_user(), and that the virtual addresses in question are contained within the lower canonical half, the guest cannot clobber any hypervisor data. Instead, Xen will take up to 2^33 pagefaults, in sequence, effectively hanging the host.

Malicious guest administrators can cause a denial of service affecting the whole system.

The Xen Project reports:

With the introduction of version 2 grant table operations, a version check became necessary for most grant table related hypercalls. The GNTTABOP_swap_grant_ref call was lacking such a check. As a result, the subsequent code behaved as if version 2 was in use, when a guest issued this hypercall without a prior GNTTABOP_setup_table or GNTTABOP_set_version.

The effect is a possible NULL pointer dereferences. However, this cannot be exploited to elevate privileges of the attacking domain, as the maximum memory address that can be wrongly accessed this way is bounded to far below the start of hypervisor memory.

Malicious or buggy guest domain kernels can mount a denial of service attack which, if successful, can affect the whole system.

The Xen Project reports:

The handler for XEN_DOMCTL_gettscinfo failed to initialize a padding field subsequently copied to guest memory.

A similar leak existed in XEN_SYSCTL_getdomaininfolist, which is being addressed here regardless of that operation being declared unsafe for disaggregation by XSA-77.

Malicious or buggy stub domain kernels or tool stacks otherwise living outside of Domain0 may be able to read sensitive data relating to the hypervisor or other guests not under the control of that domain.

The Xen Project reports:

Qemu allows guests to not only read, but also write all parts of the PCI config space (but not extended config space) of passed through PCI devices not explicitly dealt with for (partial) emulation purposes.

Since the effect depends on the specific purpose of the the config space field, it's not possible to give a general statement about the exact impact on the host or other guests. Privilege escalation, host crash (Denial of Service), and leaked information all cannot be excluded.

The Xen Project reports:

Device model code dealing with guest PCI MSI-X interrupt management activities logs messages on certain (supposedly) invalid guest operations.

A buggy or malicious guest repeatedly invoking such operations may result in the host disk to fill up, possibly leading to a Denial of Service.

The Xen Project reports:

The mask bits optionally available in the PCI MSI capability structure are used by the hypervisor to occasionally suppress interrupt delivery. Unprivileged guests were, however, nevertheless allowed direct control of these bits.

Interrupts may be observed by Xen at unexpected times, which may lead to a host crash and therefore a Denial of Service.

The Xen Project reports:

Logic is in place to avoid writes to certain host config space fields when the guest must nevertheless be able to access their virtual counterparts. A bug in how this logic deals with accesses spanning multiple fields allows the guest to write to the host MSI message data field.

While generally the writes write back the values previously read, their value in config space may have got changed by the host between the qemu read and write. In such a case host side interrupt handling could become confused, possibly losing interrupts or allowing spurious interrupt injection into other guests.

Certain untrusted guest administrators may be able to confuse host side interrupt handling, leading to a Denial of Service.

The Xen Project reports:

XSA-77 put the majority of the domctl operations on a list excepting them from having security advisories issued for them if any effects their use might have could hamper security. Subsequently some of them got declared disaggregation safe, but for a small subset this was not really correct: Their (mis-)use may result in host lockups.

As a result, the potential security benefits of toolstack disaggregation are not always fully realised.

Domains deliberately given partial management control may be able to deny service to the entire host.

As a result, in a system designed to enhance security by radically disaggregating the management, the security may be reduced. But, the security will be no worse than a non-disaggregated design.

The Xen Project reports:

HVM guests are currently permitted to modify the memory and I/O decode bits in the PCI command register of devices passed through to them. Unless the device is an SR-IOV virtual function, after disabling one or both of these bits subsequent accesses to the MMIO or I/O port ranges would - on PCI Express devices - lead to Unsupported Request responses. The treatment of such errors is platform specific.

Furthermore (at least) devices under control of the Linux pciback driver in the host are handed to guests with the aforementioned bits turned off. This means that such accesses can similarly lead to Unsupported Request responses until these flags are set as needed by the guest.

In the event that the platform surfaces aforementioned UR responses as Non-Maskable Interrupts, and either the OS is configured to treat NMIs as fatal or (e.g. via ACPI's APEI) the platform tells the OS to treat these errors as fatal, the host would crash, leading to a Denial of Service.

The Xen Project reports:

The XEN_DOMCTL_memory_mapping hypercall allows long running operations without implementing preemption.

This hypercall is used by the device model as part of the emulation associated with configuration of PCI devices passed through to HVM guests and is therefore indirectly exposed to those guests.

This can cause a physical CPU to become busy for a significant period, leading to a host denial of service in some cases.

If a host denial of service is not triggered then it may instead be possible to deny service to the domain running the device model, e.g. domain 0.

This hypercall is also exposed more generally to all toolstacks. However the uses of it in libxl based toolstacks are not believed to open up any avenue of attack from an untrusted guest. Other toolstacks may be vulnerable however.

The vulnerability is exposed via HVM guests which have a PCI device assigned to them. A malicious HVM guest in such a configuration can mount a denial of service attack affecting the whole system via its associated device model (qemu-dm).

A guest is able to trigger this hypercall via operations which it is legitimately expected to perform, therefore running the device model as a stub domain does not offer protection against the host denial of service issue. However it does offer some protection against secondary issues such as denial of service against dom0.

The Xen Project reports:

Instructions with register operands ignore eventual segment overrides encoded for them. Due to an insufficiently conditional assignment such a bogus segment override can, however, corrupt a pointer used subsequently to store the result of the instruction.

A malicious guest might be able to read sensitive data relating to other guests, or to cause denial of service on the host. Arbitrary code execution, and therefore privilege escalation, cannot be excluded.

The Xen Project reports:

The code handling certain sub-operations of the HYPERVISOR_xen_version hypercall fails to fully initialize all fields of structures subsequently copied back to guest memory. Due to this hypervisor stack contents are copied into the destination of the operation, thus becoming visible to the guest.

A malicious guest might be able to read sensitive data relating to other guests.

The Xen Project reports:

Emulation routines in the hypervisor dealing with certain system devices check whether the access size by the guest is a supported one. When the access size is unsupported these routines failed to set the data to be returned to the guest for read accesses, so that hypervisor stack contents are copied into the destination of the operation, thus becoming visible to the guest.

A malicious HVM guest might be able to read sensitive data relating to other guests.

The Xen Project reports:

When instantiating an emulated VGA device for an x86 HVM guest qemu will by default enable a backend to expose that device, either SDL or VNC depending on the version of qemu and the build time configuration.

The libxl toolstack library does not explicitly disable these default backends when they are not enabled, leading to an unexpected backend running.

If either SDL or VNC is explicitly enabled in the guest configuration then only the expected backends will be enabled.

This affects qemu-xen and qemu-xen-traditional differently.

If qemu-xen was compiled with SDL support then this would result in an SDL window being opened if $DISPLAY is valid, or a failure to start the guest if not.

If qemu-xen was compiled without SDL support then qemu would instead start a VNC server listening on ::1 (IPv6 localhost) or 127.0.0.1 (IPv4 localhost) with IPv6 preferred if available. A VNC password will not be configured even if one is present in the guest configuration.

qemu-xen-traditional will never start a vnc backend unless explicitly configured. However by default it will start an SDL backend if it was built with SDL support and $DISPLAY is valid.

The Xen Project reports:

On ARM systems the code which deals with virtualizing the GIC distributor would, under various circumstances, log messages on a guest accessible code path without appropriate rate limiting.

A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack.

The Xen Project reports:

When decoding a guest write to a specific register in the virtual interrupt controller Xen would treat an invalid value as a critical error and crash the host.

By writing an invalid value to the GICD.SGIR register a guest can crash the host, resulting in a Denial of Service attack.

OpenSSL reports:

During certificate verification, OpenSSL (starting from version 1.0.1n and 1.0.2b) will attempt to find an alternative certificate chain if the first attempt to build such a chain fails. An error in the implementation of this logic can mean that an attacker could cause certain checks on untrusted certificates to be bypassed, such as the CA flag, enabling them to use a valid leaf certificate to act as a CA and "issue" an invalid certificate.

Tim Graham reports:

In accordance with our security release policy, the Django team is issuing multiple releases -- Django 1.4.21, 1.7.9, and 1.8.3. These releases are now available on PyPI and our download page. These releases address several security issues detailed below. We encourage all users of Django to upgrade as soon as possible. The Django master branch has also been updated.

Adobe reports:

Adobe has released security updates for Adobe Flash Player. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system. Adobe is aware of a report that an exploit targeting CVE-2015-5119 has been publicly published.

ISC reports:

A very uncommon combination of zone data has been found that triggers a bug in BIND, with the result that named will exit with a "REQUIRE" failure in name.c when validating the data returned in answer to a recursive query.

A recursive resolver that is performing DNSSEC validation can be deliberately terminated by any attacker who can cause a query to be performed against a maliciously constructed zone. This will result in a denial of service to clients who rely on that resolver.

HAProxy reports:

A vulnerability was found when HTTP pipelining is used. In some cases, a client might be able to cause a buffer alignment issue and retrieve uninitialized memory contents that exhibit data from a past request or session. I want to address sincere congratulations to Charlie Smurthwaite of aTech Media for the really detailed traces he provided which made it possible to find the cause of this bug. Every user of 1.5-dev, 1.5.x or 1.6-dev must upgrade to 1.5.14 or latest 1.6-dev snapshot to fix this issue, or use the backport of the fix provided by their operating system vendors. CVE-2015-3281 was assigned to this bug.

Roundcube reports:

We just published updates to both stable versions 1.0 and 1.1 after fixing many minor bugs and adding some security improvements to the 1.1 release branch. Version 1.0.6 comes with cherry-picked fixes from the more recent version to ensure proper long term support especially in regards of security and compatibility.

The security-related fixes in particular are:

* XSS vulnerability in _mbox argument
* security improvement in contact photo handling
* potential info disclosure from temp directory

Oleg Moskalenko reports:

SQL injection security hole fixed.

Squid security advisory 2015:2 reports:

Squid configured with cache_peer and operating on explicit proxy traffic does not correctly handle CONNECT method peer responses.

The bug is important because it allows remote clients to bypass security in an explicit gateway proxy.

However, the bug is exploitable only if you have configured cache_peer to receive CONNECT requests.

Squid security advisory 2015:1 reports:

Squid configured with client-first SSL-bump does not correctly validate X509 server certificate domain / hostname fields.

The bug is important because it allows remote servers to bypass client certificate validation. Some attackers may also be able to use valid certificates for one domain signed by a global Certificate Authority to abuse an unrelated domain.

However, the bug is exploitable only if you have configured Squid to perform SSL Bumping with the "client-first" or "bump" mode of operation.

Sites that do not use SSL-Bump are not vulnerable.

All Squid built without SSL support are not vulnerable to the problem.

The FreeBSD port does not use SSL by default and is not vulnerable in the default configuration.

MITRE reports:

runner/connection_plugins/ssh.py in Ansible before 1.2.3, when using ControlPersist, allows local users to redirect a ssh session via a symlink attack on a socket file with a predictable name in /tmp/.

lib/ansible/playbook/__init__.py in Ansible 1.2.x before 1.2.3, when playbook does not run due to an error, allows local users to overwrite arbitrary files via a symlink attack on a retry file with a predictable name in /var/tmp/ansible/.

Ansible changelog reports:

Host key checking is on by default. Disable it if you like by adding host_key_checking=False in the [default] section of /etc/ansible/ansible.cfg or ~/ansible.cfg or by exporting ANSIBLE_HOST_KEY_CHECKING=False.

Gregory Maxwell reports:

On July 7th I will be making public details of several serious denial of service vulnerabilities which have fixed in recent versions of Bitcoin Core, including including CVE-2015-3641. I strongly recommend anyone running production nodes exposed to inbound connections from the internet upgrade to 0.10.2 as soon as possible.

node reports:

This release of Node.js fixes a bug that triggers an out-of-band write in V8's utf-8 decoder. This bug impacts all Buffer to String conversions. This is an important security update as this bug can be used to cause a denial of service attack.

Stefan Cornelius from Red Hat reports:

An integer overflow flaw leading to a heap-based buffer overflow was discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker being able to submit print jobs could exploit this flaw to crash texttopdf or, possibly, execute arbitrary code with the privileges of the 'lp' user.

Tim Waugh reports:

The Page allocation is moved into textcommon.c, where it does all the necessary checking: lower-bounds for CVE-2015-3258 and upper-bounds for CVE-2015-3259 due to integer overflows for the calloc() call initializing Page[0] and the memset() call in texttopdf.c's WritePage() function zeroing the entire array.

Daniel Veilland reports:

Enforce the reader to run in constant memory. One of the operation on the reader could resolve entities leading to the classic expansion issue. Make sure the buffer used for xmlreader operation is bounded. Introduce a new allocation type for the buffers for this effect.

Ignacio R. Morelle reports:

As mentioned in the Wesnoth 1.12.4 and Wesnoth 1.13.1 release announcements, a security vulnerability targeting add-on authors was found (bug #23504) which allowed a malicious user to obtain add-on server passphrases from the client's .pbl files and transmit them over the network, or store them in saved game files intended to be shared by the victim. This vulnerability affects all existing releases up to and including versions 1.12.2 and 1.13.0. Additionally, version 1.12.3 included only a partial fix that failed to guard users against attempts to read from .pbl files with an uppercase or mixed-case extension. CVE-2015-5069 and CVE-2015-5070 have been assigned to the vulnerability affecting .pbl files with a lowercase extension, and .pbl files with an uppercase or mixed-case extension, respectively.

Stefan Cornelius from Red Hat reports:

A heap-based buffer overflow was discovered in the way the texttopdf utility of cups-filters processed print jobs with a specially crafted line size. An attacker being able to submit print jobs could exploit this flaw to crash texttopdf or, possibly, execute arbitrary code.

Till Kamppeter reports:

texttopdf: Fixed buffer overflow on size allocation of texttopdf when working with extremely small line sizes, which causes the size calculation to result in 0 (CVE-2015-3258, thanks to Stefan Cornelius from Red Hat for the patch).

ntp.org reports:

Under limited and specific circumstances an attacker can send a crafted packet to cause a vulnerable ntpd instance to crash. This requires each of the following to be true:

• ntpd set up to allow for remote configuration (not allowed by default), and
• knowledge of the configuration password, and
• access to a computer entrusted to perform remote configuration.

The QEMU security team reports:

A guest which has access to an emulated PCNET network device (e.g. with "model=pcnet" in their VIF configuration) can exploit this vulnerability to take over the qemu process elevating its privilege to that of the qemu process.

Elastic reports:

Vulnerability Summary: All Elasticsearch versions from 1.0.0 to 1.5.2 are vulnerable to an attack that uses Elasticsearch to modify files read and executed by certain other applications.

Remediation Summary: Users should upgrade to 1.6.0. Alternately, ensure that other applications are not present on the system, or that Elasticsearch cannot write into areas where these applications would read.

Elastic reports:

Vulnerability Summary: All Elasticsearch versions prior to 1.5.2 and 1.4.5 are vulnerable to a directory traversal attack that allows an attacker to retrieve files from the server running Elasticsearch when one or more site plugins are installed, or when Windows is the server OS.

Remediation Summary: Users should upgrade to 1.4.5 or 1.5.2. Users that do not want to upgrade can address the vulnerability by disabling site plugins. See the CVE description for additional options.

Elastic reports:

Vulnerability Summary: Elasticsearch versions 1.3.0-1.3.7 and 1.4.0-1.4.2 have vulnerabilities in the Groovy scripting engine that were introduced in 1.3.0. The vulnerability allows an attacker to construct Groovy scripts that escape the sandbox and execute shell commands as the user running the Elasticsearch Java VM.

Remediation Summary: Users should upgrade to 1.3.8 or 1.4.3. Users that do not want to upgrade can address the vulnerability by setting script.groovy.sandbox.enabled to false in elasticsearch.yml and restarting the node.

Elastic reports:

Vulnerability Summary: Elasticsearch versions 1.3.x and prior have a default configuration for CORS that allows an attacker to craft links that could cause a user's browser to send requests to Elasticsearch instances on their local network. These requests could cause data loss or compromise.

Remediation Summary: Users should either set "http.cors.enabled" to false, or set "http.cors.allow-origin" to the value of the server that should be allowed access, such as localhost or a server hosting Kibana. Disabling CORS entirely with the former setting is more secure, but may not be suitable for all use cases.

Elastic reports:

Vulnerability Summary: In Elasticsearch versions 1.1.x and prior, dynamic scripting is enabled by default. This could allow an attacker to execute OS commands.

Remediation Summary: Disable dynamic scripting.

Logstash 1.4.2 was bundled with Elasticsearch 1.1.1, which is vulnerable to CVE-2014-3120. These binaries are used in Elasticsearch output specifically when using the node protocol. Since a node client joins the Elasticsearch cluster, the attackers could use scripts to execute commands on the host OS using the node client's URL endpoint. With 1.4.3 release, we are packaging Logstash with Elasticsearch 1.5.2 binaries which by default disables the ability to run scripts. This also affects users who are using the configuration option embedded=>true in the Elasticsearch output which starts a local embedded Elasticsearch cluster. This is typically used in development environment and proof of concept deployments. Regardless of this vulnerability, we strongly recommend not using embedded in production.

Note that users of transport and http protocol are not vulnerable to this attack.

Elastic reports:

An attacker could use the File output plugin with dynamic field references in the path option to traverse paths outside of Logstash directory. This technique could also be used to overwrite any files which can be accessed with permissions associated with Logstash user. This release sandboxes the paths which can be traversed using the configuration. We have also disallowed use of dynamic field references if the path options is pointing to an absolute path.

We have added this vulnerability to our CVE page and are working on filling out the CVE. We would like to thank Colin Coghill for reporting the issue and working with us on the resolution.

Elastic reports:

The vulnerability impacts deployments that use the either the zabbix or the nagios_nsca outputs. In these cases, an attacker with an ability to send crafted events to any source of data for Logstash could execute operating system commands with the permissions of the Logstash process.

Deployments that do not use the zabbix or the nagios_nsca outputs are not vulnerable and do not need to upgrade for this reason.

We have added this vulnerability to our CVE page and are working on filling out the CVE.

We would like to thank Jan Karwowski and Danila Borisiuk for reporting the issue and working with us on the resolution.

Elastic reports:

The combination of Logstash Forwarder and Lumberjack input (and output) was vulnerable to the POODLE attack in SSLv3 protocol. We have disabled SSLv3 for this combination and set the minimum version to be TLSv1.0. We have added this vulnerability to our CVE page and are working on filling out the CVE.

Thanks to Tray Torrance, Marc Chadwick, and David Arena for reporting this.

SSLv3 is no longer supported; TLS 1.0+ is required (compatible with Logstash 1.4.2+).

Adobe reports:

Adobe has released security updates for Adobe Flash Player for Windows, Macintosh and Linux. These updates address a critical vulnerability (CVE-2015-3113) that could potentially allow an attacker to take control of the affected system.

Adobe is aware of reports that CVE-2015-3113 is being actively exploited in the wild via limited, targeted attacks. Systems running Internet Explorer for Windows 7 and below, as well as Firefox on Windows XP, are known targets.
