Mozilla Foundation Security Advisory 2012-74

Title: Miscellaneous memory safety hazards (rv:16.0/ rv:10.0.8)
Impact: Critical
Announced: October 9, 2012
Reporter: Mozilla Developers
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 16
  Firefox ESR 10.0.8
  Thunderbird 16
  Thunderbird ESR 10.0.8
  SeaMonkey 2.13


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.


Henrik Skupin, Jesse Ruderman and moz_bug_r_a4 reported memory safety problems and crashes that affect Firefox 15.

Christian Holler and Jesse Ruderman reported memory safety problems and crashes that affect Firefox ESR 10 and Firefox 15.
