Mozilla Foundation Security Advisory 2013-47

Title: Uninitialized functions in DOMSVGZoomEvent
Impact: High
Announced: May 14, 2013
Reporter: Ms2ger
Products: Firefox, Thunderbird

Fixed in: Firefox 21.0
  Firefox ESR 17.0.6
  Thunderbird 17.0.6
  Thunderbird ESR 17.0.6

Description

Mozilla community member Ms2ger discovered that some DOMSVGZoomEvent functions are used without being properly initialized, causing uninitialized memory to be used when they are called by web content. This could lead to a information leakage to sites depending on the contents of this uninitialized memory.

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.
