Mozilla Foundation Security Advisory 2013-26

Title: Use-after-free in nsImageLoadingContent
Impact: Critical
Announced: February 19, 2013
Reporter: Nils
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 19.0
  Firefox ESR 17.0.3
  Thunderbird 17.0.3
  Thunderbird ESR 17.0.3
  SeaMonkey 2.16

Description

Security researcher Nils reported a use-after-free in nsImageLoadingContent when content script is executed. This could allow for arbitrary code execution.

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.
