Mozilla Foundation Security Advisory 2009-65
Title: Crashes with evidence of memory corruption (rv:1.9.1.6/ 1.9.0.16)
Impact: Critical
Announced: December 15, 2009
Reporter: Mozilla developers and community
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 3.5.6
Firefox 3.0.16
SeaMonkey 2.0.1
Description
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.
Workaround
Disable JavaScript until a version containing these fixes can be installed.
