Mozilla Foundation Security Advisory 2013-13
Title: Memory corruption in XBL with XML bindings containing SVG
Announced: January 8, 2013
Reporter: Sviatoslav Chagaev
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 18.0
Firefox ESR 17.0.2
Thunderbird ESR 17.0.2
Security researcher Sviatoslav Chagaev reported that when using an XBL file containing multiple XML bindings with SVG content, a memory corruption can occur. In concern with remote XUL, this can lead to an exploitable crash.
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.
