Mozilla Foundation Security Advisory 2012-42
Title: Miscellaneous memory safety hazards
Announced: July 17, 2012
Reporter: Mozilla Developers
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 14
Firefox ESR 10.0.6
Thunderbird ESR 10.0.6
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.
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.
Brian Smith, Gary Kwong, Christian Holler, Jesse Ruderman, Christoph Diehl, Chris Jones, Brad Lassey, and Kyle Huey reported memory safety problems and crashes that affect Firefox 13.
Benoit Jacob, Jesse Ruderman, Christian Holler, and Bill McCloskey reported memory safety problems and crashes that affect Firefox ESR 10 and Firefox 13.
