Monkey HTTP Server before 1.5.3, when the File Descriptor Table (FDT) is enabled and custom error messages are set, allows remote attackers to cause a denial of service (file descriptor consumption) via an HTTP request that triggers an error message.

Mozilla Firefox before 18.0 on Android and SeaMonkey before 2.15 do not restrict a touch event to a single IFRAME element, which allows remote attackers to obtain sensitive information or possibly conduct cross-site scripting (XSS) attacks via a crafted HTML document.

Mozilla Firefox before 3.6.26 and 4.x through 6.0, Thunderbird before 3.1.18 and 5.0 through 6.0, and SeaMonkey before 2.4 do not properly enforce the IPv6 literal address syntax, which allows remote attackers to obtain sensitive information by making XMLHttpRequest calls through a proxy and reading the error messages.

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.

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.
