Mozilla Firefox before 3.6.20, SeaMonkey 2.x, Thunderbird 3.x before 3.1.12, and possibly other products does not properly handle the dropping of a tab element, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges by establishing a content area and registering for drop events.

Mozilla Firefox before 3.6.20, Thunderbird 2.x and 3.x before 3.1.12, SeaMonkey 1.x and 2.x, and possibly other products does not properly handle the RegExp.input property, which allows remote attackers to bypass the Same Origin Policy and read data from a different domain via a crafted web site, possibly related to a use-after-free.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.20, Thunderbird 2.x and 3.x before 3.1.12, SeaMonkey 1.x and 2.x, and possibly other products allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The event-management implementation in Mozilla Firefox before 3.6.20, SeaMonkey 2.x, Thunderbird 3.x before 3.1.12, and possibly other products does not properly select the context for script to run in, which allows remote attackers to bypass the Same Origin Policy or execute arbitrary JavaScript code with chrome privileges via a crafted web site.

The appendChild function in Mozilla Firefox before 3.6.20, Thunderbird 3.x before 3.1.12, SeaMonkey 2.x, and possibly other products does not properly handle DOM objects, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to dereferencing of a "dangling pointer."

The SVGTextElement.getCharNumAtPosition function in Mozilla Firefox before 3.6.20, and 4.x through 5; Thunderbird 3.x before 3.1.12 and other versions before 6; SeaMonkey 2.x before 2.3; and possibly other products does not properly handle SVG text, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to a "dangling pointer."

Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a multipart/x-mixed-replace image.

Use-after-free vulnerability in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14, when JavaScript is disabled, allows remote attackers to execute arbitrary code via a crafted XUL document.

Integer overflow in the Array.reduceRight method in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to execute arbitrary code via vectors involving a long JavaScript Array object.

Use-after-free vulnerability in the nsSVGPointList::AppendElement function in the implementation of SVG element lists in Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors involving a user-supplied callback.

Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 do not distinguish between cookies for two domain names that differ only in a trailing dot, which allows remote web servers to bypass the Same Origin Policy via Set-Cookie headers.

Use-after-free vulnerability in the nsXULCommandDispatcher function in Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to execute arbitrary code via a crafted XUL document that dequeues the current command updater.

Use-after-free vulnerability in the nsSVGPathSegList::ReplaceItem function in the implementation of SVG element lists in Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors involving a user-supplied callback.

Google Chrome before 10.0.648.127 allows remote attackers to bypass the Same Origin Policy via unspecified vectors, related to an "error message leak."
