Mozilla Foundation Security Advisory 2010-74

Title: Miscellaneous memory safety hazards (rv:1.9.2.13/ 1.9.1.16)
Impact: Critical
Announced: December 9, 2010
Reporter: Mozilla developers and community
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 3.6.13
  Firefox 3.5.16, Firefox 3.5.17
  Thunderbird 3.1.7
  Thunderbird 3.0.11
  SeaMonkey 2.0.11

Description

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.

Update (March 1, 2011): CVE-2010-3777 was fixed in Firefox 3.5.17
