A potentially exploitable crash in "EnumerateSubDocuments" while adding or removing sub-documents. This vulnerability affects Firefox ESR < 45.6 and Thunderbird < 45.6.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 47.0 and Firefox ESR 45.x before 45.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
ImageMagick 6.7.5-7 and earlier allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via crafted offset and count values in the ResolutionUnit tag in the EXIF IFD0 of an image.
Use-after-free vulnerability in Mozilla Firefox before 17.0, Firefox ESR 10.x before 10.0.11, Thunderbird before 17.0, Thunderbird ESR 10.x before 10.0.11, and SeaMonkey before 2.14 on Mac OS X allows remote attackers to execute arbitrary code via an HTML document.

Tavis Ormandy and Julien Tinnes, Google Security Team reported that Kernels <= 2.6.18.8 are vulnerable to a NULL pointer dereference issue when using MSGMORE on udp sockets.
Fixed upstream already by: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=1e0c14f49d6b393179f423abbac47f85618d3d46

Description of problem: Reported by Tavis Ormandy and Julien Tinnes. The SOCKOPSWRAP macro from include/linux/net.h doesn't initialise the sendpage operation in the protoops structure correctly. Leading to a kernel NULL pointer dereference, and thus a local privilege escalation.

It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation before 2.6.22.17 used the IPv4-only inetskrebuildheader() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system.
Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
WebExtension scripts can use the "data:" protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions. This vulnerability affects Firefox ESR < 45.7 and Firefox < 51.
Memory corruption resulting in a potentially exploitable crash during WebGL functions using a vector constructor with a varying array within libGLES.
An attacker could use a JavaScript Map/Set timing attack to determine whether an atom is used by another compartment/zone in specific contexts. This could be used to leak information, such as usernames embedded in JavaScript code, across websites.
External resources that should be blocked when loaded by SVG images can bypass security restrictions through the use of "data:" URLs. This could allow for cross-domain data leakage. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.
The Pocket toolbar button, once activated, listens for events fired from it's own pages but does not verify the origin of incoming events. This allows content from other origins to fire events and inject content and commands into the Pocket context. Note: this issue does not affect users with e10s enabled.
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUSSTARTPACKET set and then a crafted packet with TXSTATUSDEVICEOWNS set.
A defect in BIND's handling of responses containing a DNAME answer can cause a resolver to exit after encountering an assertion failure in db.c or resolver.c
During processing of a recursive response that contains a DNAME record in the answer section, BIND can stop execution after encountering an assertion error in resolver.c (error message: "INSIST((valoptions & 0x0002U) != 0) failed") or db.c (error message: "REQUIRE(targetp != ((void )0) && targetp == ((void )0)) failed").
A server encountering either of these error conditions will stop, resulting in denial of service to clients. The risk to authoritative servers is minimal; recursive servers are chiefly at risk.
Same-origin policy protections can be bypassed on pages with embedded iframes during page reloads, allowing the iframes to access content on the top level page, leading to information disclosure.
Unspecified vulnerability in Oracle MySQL Server 5.5.44 and earlier, and 5.6.25 and earlier, allows local users to affect confidentiality, integrity, and availability via unknown vectors related to Client programs.
In both triggerscan and schedscan operations, we were checking for the SSID length before assigning the value correctly. Since the memory was just kzalloc'ed, the check was always failing and SSID with over 32 characters were allowed to go through.
This is causing a buffer overflow when copying the actual SSID to the proper place.

Array index error in the gdthreadevent function in drivers/scsi/gdth.c in the Linux kernel before 2.6.32-rc8 allows local users to cause a denial of service or possibly gain privileges via a negative event index in an IOCTL request.
The pollmodeio file for the megaraidsas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.
Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc//fd/ pathname.
