Title: Heap memory corruption issues found using Address Sanitizer
Impact: Critical
Announced: October 9, 2012
Reporter: Atte Kettunen
Products: Firefox, Thunderbird, SeaMonkey

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

Description

Security researcher Atte Kettunen from OUSPG reported several heap memory corruption issues found using the Address Sanitizer tool. These issues are potentially exploitable, allowing for remote code execution.

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.
