Mozilla Foundation Security Advisory 2013-90
Title: Memory corruption involving scrolling
Announced: September 17, 2013
Products: Firefox, Thunderbird, Seamonkey
Fixed in: Firefox 24.0
Firefox ESR 17.0.9
Thunderbird ESR 17.0.9
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.
