Mozilla Firefox — свободный браузер на движке Gecko

Mozilla Firefox before 31.0 and Thunderbird before 31.0 do not properly implement the sandbox attribute of the IFRAME element, which allows remote attackers to bypass intended restrictions on same-origin content via a crafted web site in conjunction with a redirect.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The mozilla::dom::AudioBufferSourceNodeEngine::CopyFromInputBuffer function in Mozilla Firefox before 31.0 and Thunderbird before 31.0 does not properly allocate Web Audio buffer memory, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via crafted audio content that is improperly handled during playback buffering.

The ConvolveHorizontally function in Skia, as used in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7, does not properly handle the discarding of image data during function execution, which allows remote attackers to execute arbitrary code by triggering prolonged image scaling, as demonstrated by scaling of a high-quality image.

Use-after-free vulnerability in the MediaInputPort class in Mozilla Firefox before 31.0 and Thunderbird before 31.0 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) by leveraging incorrect Web Audio control-message ordering.

Mozilla Firefox before 31.0 and Thunderbird before 31.0 allow remote attackers to cause a denial of service (X.509 certificate parsing outage) via a crafted certificate that does not use UTF-8 character encoding in a required context, a different vulnerability than CVE-2014-1559.

Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 allow remote attackers to execute arbitrary code via crafted WebGL content constructed with the Cesium JavaScript library.

Use-after-free vulnerability in the nsDocLoader::OnProgress function in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 allows remote attackers to execute arbitrary code via vectors that trigger a FireOnStateChange event.

Mozilla Firefox before 31.0 does not properly restrict use of drag-and-drop events to spoof customization events, which allows remote attackers to alter the placement of UI icons via crafted JavaScript code that is encountered during (1) page, (2) panel, or (3) toolbar customization.

Mozilla Firefox before 31.0 and Thunderbird before 31.0 allow remote attackers to cause a denial of service (X.509 certificate parsing outage) via a crafted certificate that does not use ASCII character encoding in a required context.
