Mozilla Firefox — свободный браузер на движке Gecko

Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 do not prevent use of the valueOf method to shadow the location object (aka window.location), which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via vectors involving a plugin.

Mozilla Firefox before 16.0.2, Firefox ESR 10.x before 10.0.10, Thunderbird before 16.0.2, Thunderbird ESR 10.x before 10.0.10, and SeaMonkey before 2.13.2 allow remote attackers to bypass the Same Origin Policy and read the Location object via a prototype property-injection attack that defeats certain protection mechanisms for this object.

The XrayWrapper implementation in Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 does not consider the compartment during property filtering, which allows remote attackers to bypass intended chrome-only restrictions on reading DOM object properties via a crafted web site.

Use-after-free vulnerability in Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, and SeaMonkey before 2.13 might allow user-assisted remote attackers to execute arbitrary code via vectors involving use of mozRequestFullScreen to enter full-screen mode, and use of the history.back method for backwards history navigation.

Use-after-free vulnerability in the nsEditor::FindNextLeafNode function in Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.

The str_unescape function in the JavaScript engine in Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via unspecified vectors.

Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving the setting of Cascading Style Sheets (CSS) properties in conjunction with SVG text.

Use-after-free vulnerability in the nsViewManager::ProcessPendingUpdates function in Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The copyTexImage2D implementation in the WebGL subsystem in Mozilla Firefox before 17.0, Thunderbird before 17.0, and SeaMonkey before 2.14 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via large image dimensions.
