Mozilla Foundation Security Advisory 2013-90

Title: Memory corruption involving scrolling
Impact: Critical
Announced: September 17, 2013
Reporter: Nils
Products: Firefox, Thunderbird, Seamonkey

Fixed in: Firefox 24.0
  Firefox ESR 17.0.9
  Thunderbird 24.0
  Thunderbird ESR 17.0.9
  Seamonkey 2.21


Security researcher Nils reported two potentially exploitable memory corruption bugs involving scrolling. The first was a use-after-free condition due to scrolling an image document. The second was due to nodes in a range request being added as children of two different parents.

In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but are potentially a risk in browser or browser-like contexts.
