Title: Mozilla SVG Processing Remote Code Execution
Impact: Critical
Announced: December 19, 2006

Products: Firefox 1.5.0.4, SeaMonkey

Fixed in: Firefox 2.0.0.1

Description

Appending an SVG comment DOM node from one document into another type of document such as HTML in some cases results in a crash due to memory corruption that can be exploited to run arbitrary code.

This flaw was introduced in the Firefox 1.5.0.4 release, prior versions are unaffected.

Mozilla would like to thank an anonymous researcher working with TippingPoint and the Zero Day Initiative for reporting this issue.

Workaround

Disable JavaScript until you can upgrade to a fixed version.
