Mozilla Foundation Security Advisory 2009-65
Title: Crashes with evidence of memory corruption (rv:220.127.116.11/ 18.104.22.168)
Announced: December 15, 2009
Reporter: Mozilla developers and community
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 3.5.6
Mozilla developers and community members identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes 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.
Jesse Ruderman, Josh Soref, Martijn Wargers, Jose Angel, and Olli Pettay reported crashes in the browser engine which affected both Firefox 3 and Firefox 3.5.
Jeremy Lea and Jesse Ruderman reported crashes in the browser engine which only affected Firefox 3.5.
Jesse Ruderman also reported a crash in the browser engine which only affected Firefox 3.
