Mozilla Foundation Security Advisory 2013-01

Title: Miscellaneous memory safety hazards (rv:18.0/ rv:10.0.12 / rv:17.0.2)
Impact: Critical
Announced: January 8, 2013
Reporter: Mozilla Developers
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 18.0
  Firefox ESR 10.0.12
  Firefox ESR 17.0.2
  Thunderbird 17.0.2
  Thunderbird ESR 10.0.12
  Thunderbird ESR 17.0.2
  SeaMonkey 2.15

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.

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.
