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 we presume that with enough effort at least some of these could be exploited to run arbitrary code.

Update (March 1, 2011): CVE-2010-3777 was fixed in Firefox 3.5.17


Jesee Ruderman, Andreas Gal, Nils, and Brian Hackett reported memory safety problems that affected Firefox 3.6 and Firefox 3.5.

Igor Bukanov reported a memory safety problem that was fixed in Firefox 3.6 only.

Jesse Ruderman reported a crash which affected Firefox 3.5 only.
