Mozilla Foundation Security Advisory 2013-95

Title: Access violation with XSLT and uninitialized data
Impact: High
Announced: October 29, 2013
Reporter: Abhishek Arya
Products: Firefox, Thunderbird, Seamonkey

Fixed in: Firefox 25.0
  Firefox ESR 24.1
  Firefox ESR 17.0.10
  Thunderbird 24.1
  Thunderbird ESR 17.0.10
  Seamonkey 2.22


Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover an access violation due to uninitialized data during Extensible Stylesheet Language Transformation (XSLT) processing. This leads to a potentially exploitable crash.

In general this flaw cannot be exploited through email in the Thunderbird and Seamonkey products because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
