Mozilla: Out-of-bounds read during 2D canvas display on Linux 16-bit color depth systems (MFSA 2015-107)

gfx/2d/DataSurfaceHelpers.cpp in Mozilla Firefox before 41.0 on Linux improperly attempts to use the Cairo library with 32-bit color-depth surface creation followed by 16-bit color-depth surface display, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) by using a CANVAS element to trigger 2D rendering.

Mozilla: Buffer overflow while decoding WebM video (MFSA 2015-105)

Heap-based buffer overflow in the nestegg_track_codec_data function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allows remote attackers to execute arbitrary code via a crafted header in a WebM video.

Mozilla: Use-after-free with shared workers and IndexedDB (MFSA 2015-104)

Race condition in the WorkerPrivate::NotifyFeatures function in Mozilla Firefox before 41.0 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and application crash) by leveraging improper interaction between shared workers and the IndexedDB implementation.

Mozilla: Use-after-free while manipulating HTML media content (MFSA 2015-106)

Use-after-free vulnerability in the HTMLVideoElement interface in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allows remote attackers to execute arbitrary code via crafted JavaScript code that modifies the URI table of a media element, aka ZDI-CAN-3176.

Mozilla: URL spoofing in reader mode (MFSA 2015-103)

Mozilla Firefox before 41.0, when reader mode is enabled, allows remote attackers to spoof the relationship between address-bar URLs and web content via a crafted web site.

Mozilla: Crash when using debugger with SavedStacks in JavaScript (MFSA 2015-102)

The SavedStacks class in the JavaScript implementation in Mozilla Firefox before 41.0, when the Debugger API is enabled, allows remote attackers to cause a denial of service (getSlotRef assertion failure and application exit) or possibly execute arbitrary code via a crafted web site.

Mozilla: Buffer overflow in libvpx while parsing vp9 format video (MFSA 2015-101)

Buffer overflow in the vp9_init_context_buffers function in libvpx, as used in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3, allows remote attackers to execute arbitrary code via a crafted VP9 file.

Mozilla: Arbitrary file manipulation by local user through Mozilla updater (MFSA 2015-100)

updater.exe in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 on Windows allows local users to write to arbitrary files by conducting a junction attack and waiting for an update operation by the Mozilla Maintenance Service.

Mozilla: Out of bounds read in QCMS library with ICC V4 profile attributes (MFSA 2015-98)

The lut_inverse_interp16 function in the QCMS library in Mozilla Firefox before 41.0 allows remote attackers to obtain sensitive information or cause a denial of service (buffer over-read and application crash) via crafted attributes in the ICC 4 profile of an image.

Mozilla: Memory leak in mozTCPSocket to servers (MFSA 2015-97)

The TCP Socket API implementation in Mozilla Firefox before 41.0 mishandles array boundaries that were established with a navigator.mozTCPSocket.open method call and send method calls, which allows remote TCP servers to obtain sensitive information from process memory by reading packet data, as demonstrated by availability of this API in a Firefox OS application.

Mozilla: Scripted proxies can access inner window (MFSA 2015-108)

js/src/proxy/Proxy.cpp in Mozilla Firefox before 41.0 mishandles certain receiver arguments, which allows remote attackers to bypass intended window access restrictions via a crafted web site.

Mozilla: JavaScript garbage collection crash with Java applet (MFSA 2015-130)

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4, when a Java plugin is enabled, allow remote attackers to cause a denial of service (incorrect garbage collection and application crash) or possibly execute arbitrary code via a crafted Java applet that deallocates an in-use JavaScript wrapper.

Mozilla: Miscellaneous memory safety hazards (MFSA 2015-96)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 41.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla: Miscellaneous memory safety hazards (MFSA 2015-96)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Util.pm in Bugzilla 2.x, 3.x, and 4.x before 4.2.15, 4.3.x and 4.4.x before 4.4.10, and 5.x before 5.0.1 mishandles long e-mail addresses during account registration, which allows remote attackers to obtain the default privileges for an arbitrary domain name by placing that name in a substring of an address, as demonstrated by truncation of an @mozilla.com.example.com address to an @mozilla.com address.
