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.
In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

Not Vulnerable. This issue does not affect the version of Firefox and Thunderbird package as shipped with Red Hat Enterprise Linux 5 and 6.
Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Brian Smith, Gary Kwong, Christian Holler, Jesse Ruderman, Christoph Diehl, Chris Jones, Brad Lassey, and Kyle Huey as the original reporters.
