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.

Heap-based buffer overflow in the nsTransformedTextRun 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 execute arbitrary code via Cascading Style Sheets (CSS) token sequences that trigger changes to capitalization style.

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.

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.

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.

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.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The fetch API implementation in Mozilla Firefox before 41.0.2 does not restrict access to the HTTP response body in certain situations where user credentials are supplied but the CORS cross-origin request algorithm is improperly followed, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.
