Mozilla Foundation Security Advisory 2009-01
Title: Crashes with evidence of memory corruption (rv:22.214.171.124)
Announced: February 3, 2009
Reporter: Mozilla developers
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 3.0.6
Mozilla developers 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, Georgi Guninski, and Martijn Wargers reported crashes in the layout engine.
