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.
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.
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.
Unspecified vulnerability in the browser engine in Mozilla Firefox 3.6.x before 3.6.17 and 4.x before 4.0.1, and Thunderbird 3.1.x before 3.1.10, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
The line-breaking implementation in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, Thunderbird before 3.0.11 and 3.1.x before 3.1.7, and SeaMonkey before 2.0.11 on Windows does not properly handle long strings, which allows remote attackers to execute arbitrary code via a crafted document.write call that triggers a buffer over-read.
Unspecified vulnerability in Mozilla Firefox 3.6.x before 3.6.13 and Thunderbird 3.1.x before 3.1.7 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
The nsDocShell::OnRedirectStateChange function in docshell/base/nsDocShell.cpp in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, and SeaMonkey before 2.0.6, allows remote attackers to spoof the SSL security status of a document via vectors involving multiple requests, a redirect, and the history.back and history.forward JavaScript functions.
Integer overflow in an array class in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 allows remote attackers to execute arbitrary code by placing many Cascading Style Sheets (CSS) values in an array, related to references to external font resources and an inconsistency between 16-bit and 32-bit integers.
Use-after-free vulnerability in the NodeIterator implementation in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, and SeaMonkey before 2.0.6, allows remote attackers to execute arbitrary code via a crafted NodeFilter that detaches DOM nodes, related to the NodeIterator interface and a javascript callback.
