Mozilla Firefox before 9.0, Thunderbird before 9.0, and SeaMonkey before 2.6 on Mac OS X do not properly handle certain DOM frame deletions by plugins, which allows remote attackers to cause a denial of service (incorrect pointer dereference and application crash) or possibly have unspecified other impact via a crafted web site.

Mozilla Firefox 4.x through 8.0, Thunderbird 5.0 through 8.0, and SeaMonkey before 2.6 allow remote attackers to capture keystrokes entered on a web page, even when JavaScript is disabled, by using SVG animation accessKey events within that web page.

YARR, as used in Mozilla Firefox 4.x through 8.0, Thunderbird 5.0 through 8.0, and SeaMonkey before 2.6, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted JavaScript.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 4.x through 8.0, Thunderbird 5.0 through 8.0, and SeaMonkey before 2.6 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors that trigger a compartment mismatch associated with the nsDOMMessageEvent::GetData function, and unknown other vectors.

The browser engine in Mozilla Firefox before 8.0 and Thunderbird before 8.0 does not properly handle links from SVG mpath elements to non-SVG elements, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.

Mozilla Firefox before 8.0 and Thunderbird before 8.0 on Mac OS X do not properly interact with the GPU memory behavior of a certain driver for Intel integrated GPUs, which allows remote attackers to bypass the Same Origin Policy and read image data via vectors related to WebGL textures.

The browser engine in Mozilla Firefox before 8.0 and Thunderbird before 8.0 does not properly allocate memory, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.

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."
