Untrusted search path vulnerability in the installer in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, and Thunderbird ESR 10.x before 10.0.7 on Windows allows local users to gain privileges via a Trojan horse executable file in a root directory.

Summer Institute of Linguistics (SIL) Graphite 2, as used in Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before 2.12, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to the (1) Silf::readClassMap and (2) Pass::readPass functions.

Use-after-free vulnerability in the nsHTMLEditRules::DeleteNonTableElements function in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.

Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 do not properly iterate through the characters in a text run, which allows remote attackers to execute arbitrary code via a crafted 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.

Mozilla Firefox before 3.6.25 and Thunderbird before 3.1.17 on Mac OS X do not consider .jar files to be executable files, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted file. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-2372 on Mac OS X.

The JavaScript implementation in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 does not properly restrict the set of values contained in the object returned by the getComputedStyle method, which allows remote attackers to obtain sensitive information about visited web pages by calling this method.

The layout engine in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 executes different code for visited and unvisited links during the processing of Cascading Style Sheets (CSS) token sequences, which makes it easier for remote attackers to obtain sensitive information about visited web pages via a timing attack.

The Cascading Style Sheets (CSS) implementation in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.
