Multiple untrusted search path vulnerabilities in updater.exe in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 on Windows, when the Maintenance Service is not used, allow local users to gain privileges via a Trojan horse DLL in (1) the current working directory or (2) a temporary directory, as demonstrated by bcrypt.dll.

Use-after-free vulnerability in the mozilla::dom::IndexedDB::IDBObjectStore::CreateIndex function in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via crafted content that is improperly handled during IndexedDB index creation.

Heap-based buffer overflow in the mozilla::gfx::CopyRect function in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 allows remote attackers to obtain sensitive information from uninitialized process memory via a malformed SVG graphic.

The Form Autocompletion feature in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 allows remote attackers to read arbitrary files via crafted JavaScript code.

Use-after-free vulnerability in the WebRTC implementation in Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, and SeaMonkey before 2.32 allows remote attackers to execute arbitrary code via crafted track data.

Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, Thunderbird before 31.4, and SeaMonkey before 2.32 do not properly interpret Set-Cookie headers within responses that have a 407 (aka Proxy Authentication Required) status code, which allows remote HTTP proxy servers to conduct session fixation attacks by providing a cookie name that corresponds to the session cookie of the origin server.

The navigator.sendBeacon implementation in Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, Thunderbird before 31.4, and SeaMonkey before 2.32 omits the CORS Origin header, which allows remote attackers to bypass intended CORS access-control checks and conduct cross-site request forgery (CSRF) attacks via a crafted web site.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, Thunderbird before 31.4, and SeaMonkey before 2.32 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, and Thunderbird before 31.3 on Apple OS X 10.10 omit a CoreGraphics disable-logging action that is needed by jemalloc-based applications, which allows local users to obtain sensitive information by reading /tmp files, as demonstrated by credential information.

Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 might allow remote attackers to execute arbitrary code by leveraging an incorrect cast from the BasicThebesLayer data type to the BasicContainerLayer data type.

Stack-based buffer overflow in the mozilla::FileBlockCache::Read function in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allows remote attackers to execute arbitrary code via crafted media content.

Use-after-free vulnerability in the nsHtml5TreeOperation function in xul.dll in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allows remote attackers to execute arbitrary code by adding a second root element to an HTML5 document during parsing.

The XMLHttpRequest.prototype.send method in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allows remote attackers to cause a denial of service (application crash) via a crafted JavaScript object.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

content/base/src/nsDocument.cpp in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 does not consider whether WebRTC video sharing is occurring, which allows remote attackers to obtain sensitive information from the local camera in certain IFRAME situations by maintaining a session after the user temporarily navigates away.

The WebRTC video-sharing feature in dom/media/MediaManager.cpp in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 does not properly recognize Stop Sharing actions for videos in IFRAME elements, which allows remote attackers to obtain sensitive information from the local camera by maintaining a session after the user tries to discontinue streaming.

The Alarm API in Mozilla Firefox before 33.0 and Firefox ESR 31.x before 31.2 does not properly restrict toJSON calls, which allows remote attackers to bypass the Same Origin Policy via crafted API calls that access sensitive information within the JSON data of an alarm.

Use-after-free vulnerability in DirectionalityUtils.cpp in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allows remote attackers to execute arbitrary code via text that is improperly handled during the interaction between directionality resolution and layout.

The get_tile function in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly execute arbitrary code via WebM frames with invalid tile sizes that are improperly handled in buffering operations during video playback.

The mozilla::dom::OscillatorNodeEngine::ComputeCustom function in the Web Audio subsystem in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read, memory corruption, and application crash) via an invalid custom waveform that triggers a calculation of a negative frequency value.
