Mozilla Foundation Security Advisory 2009-64
Title: Crashes with evidence of memory corruption (rv:220.127.116.11/ 18.104.22.168)
Announced: October 27, 2009
Reporter: Mozilla developers and community
Fixed in: Firefox 3.5.4
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.
Vladimir Vukicevic, Jesse Ruderman, Martijn Wargers, Daniel Banchero, David Keeler, and Boris Zbarsky reported crashes in the browser engine which affected both Firefox 3 and Firefox 3.5.
Thomas Frederiksen, Marcia Knous, Jesse Ruderman, Carsten Book, and Kevin Brosnan reported crashes in the browser engine which affected only Firefox 3.5.
Carsten Book reported a crash in the browser engine which affected only Firefox 3.
