Mozilla Foundation Security Advisory 2010-34

Title: Miscellaneous memory safety hazards (rv:
Impact: Critical
Announced: July 20, 2010
Reporter: Mozilla developers and community
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 3.6.7
  Firefox 3.5.11
  Thunderbird 3.1.1
  Thunderbird 3.0.6
  SeaMonkey 2.0.6


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.


Jesse Ruderman, Ehsan Akhgari, Mats Palmgren, Igor Bukanov, Gary Kwong, Tobias Markus and Daniel Holbert reported memory safety problems that affected Firefox 3.6 and Firefox 3.5.

Jesse Ruderman, David Anderson and Johnny Stenback reported memory safety problems that affected Firefox 3.6 only.
