Mozilla Foundation Security Advisory 2013-69

Title: CRMF requests allow for code execution and XSS attacks
Impact: Critical
Announced: August 6, 2013
Reporter: moz_bug_r_a4
Products: Firefox, Thunderbird, Seamonkey

Fixed in: Firefox 23.0
  Firefox ESR 17.0.8
  Thunderbird 17.0.8
  Thunderbird ESR 17.0.8
  Seamonkey 2.20


Mozilla security researcher moz_bug_r_a4 reported a mechanism to execute arbitrary code or a cross-site scripting (XSS) attack when Certificate Request Message Format (CRMF) request is generated in certain circumstances.

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.
