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.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent the starting of a download in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site.

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not properly handle HTTP responses that contain multiple Location, Content-Length, or Content-Disposition headers, which makes it easier for remote attackers to conduct HTTP response splitting attacks via crafted header values.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Use-after-free vulnerability in Mozilla Firefox 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OGG headers in a .ogg file.

Mozilla Firefox 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent manual add-on installation in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site that triggers an unspecified internal error.

YARR, as used in Mozilla Firefox before 7.0, Thunderbird before 7.0, and SeaMonkey before 2.4, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted JavaScript.
