Mozilla Firefox Bugs Let Remote Users Conduct Cross-Site Request Forgery Attacks and Execute Arbitrary Code.
Firefox, Thunderbird, SeaMonkey
Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and Mozilla presume that with enough effort at least some of these could be exploited to run arbitrary code.
A weakness and some vulnerabilities have been reported in Mozilla Firefox and SeaMonkey, which can be exploited by malicious people to conduct spoofing attacks, cross-site request forgery attacks, and compromise a user's system.
1) Multiple errors in the browser engine can be exploited to corrupt memory and potentially execute arbitrary code.
2) An error when handling recursive calls to "eval()" within a "try/catch" statement can lead to dialogs being displayed incorrectly and returning "true" when being closed. This can e.g. be exploited to gain escalated privileges by forcing a user into accepting certain dialogs.
3) A use-after-free error related to "JSON.stringify" can be exploited to execute arbitrary code.
7) An error when allocating memory for layout objects displaying long strings can be exploited to cause a memory corruption and execute arbitrary code.Note: This may only affect the Windows platform.
9) An error when decoding certain JPEG images can be exploited to cause a buffer overflow and potentially execute arbitrary code.Note: This does not affect the Mozilla Firefox 3.5 branch.
10) When a request initiated by the plugin received a redirect response (307), the request including any custom headers is incorrectly forwarded to the new location without notifying the plugin, which can be used to e.g. bypass cross-site request forgery protections relying on custom headers.
