Description

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.

Peter Van der Beken, Jason Oster, Jesse Ruderman, Igor Bukanov, Jeff Walden, Gary Kwong and Olli Pettay reported memory safety problems that affected Firefox 3.6 and Firefox 3.5.

Also, special thanks to Michal Zalewski whose contributions helped identify two of the security bugs fixed in this release.
