Mandriva Linux Security Advisory 2010-251 - Security researchers Yosuke Hasegawa and Masatoshi Kimura reported that the x-mac-arabic, x-mac-farsi and x-mac-hebrew character encodings are vulnerable to XSS attacks due to some characters being converted to angle brackets when displayed by the rendering engine. Google security researcher Michal Zalewski reported that when a window was opened to a site resulting in a network or certificate error page, the opening site could access the document inside the opened window and inject arbitrary content. Various other security issues were identified and fixed in Firefox.

Google security researcher Michal Zalewski reported that when a window was opened to a site resulting in a network or certificate error page, the opening site could access the document inside the opened window and inject arbitrary content. An attacker could use this bug to spoof the location bar and trick a user into thinking they were on a different site than they actually were. Mozilla security researcher moz_bug_r_a4 reported that the fix for could be circumvented permitting the execution of arbitrary JavaScript with chrome privileges. Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that JavaScript arrays were vulnerable to an integer overflow vulnerability. Various other security issues were addressed in Firefox.

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. Various other vulnerabilities have been addressed in Mozilla Thunderbird.
