Firefox 3.0.8

What’s New in Firefox 3.0.8

Firefox 3.0.8 fixes two critical security issues found in Firefox 3.0.7:

Mozilla Foundation Security Advisory 2009-13

Title: Arbitrary code execution via XUL tree element
Impact: Critical
Announced: March 27, 2009
Reporter: Nils
Products: Firefox
Fixed in: Firefox 3.0.8


Security researcher Nils reported via TippingPoint’s Zero Day Initiative that the XUL tree method _moveToEdgeShift was in some cases triggering garbage collection routines on objects which were still in use. In such cases, the browser would crash when attempting to access a previously destroyed object and this crash could be used by an attacker to run arbitrary code on a victim’s computer.

This vulnerability was used by the reporter to win the 2009 CanSecWest Pwn2Own contest.
This vulnerability does not affect Firefox 2.

Mozilla Foundation Security Advisory 2009-12

Title: XSL Transformation vulnerability
Impact: Critical
Announced: March 27, 2009
Reporter: Guido Landi, Andre, Michael Rooney, Martin
Products: Firefox
Fixed in: Firefox 3.0.8


Security researcher Guido Landi discovered that a XSL stylesheet could be used to crash the browser during a XSL transformation. An attacker could potentially use this crash to run arbitrary code on a victim’s computer.

This vulnerability was also previously reported as a stability problem by Ubuntu community member, Andre. Ubuntu community member Michael Rooney reported Andre’s findings to Mozilla, and Mozilla community member Martin helped reduce Andre’s original testcase and contributed a patch to fix the vulnerability.
