Mozilla Foundation Security Advisory 2013-16

Title: Use-after-free in serializeToStream
Impact: Critical
Announced: January 8, 2013
Reporter: regenrecht
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

Security researcher regenrecht reported, via TippingPoint's Zero Day Initiative, a use-after-free in XMLSerializer by the exposing of serializeToStream to web content. This can lead to arbitrary code execution when exploited.

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.
