Mozilla Releases Firefox 3.6.3

Fixed in: Firefox 3.6.3

Description

A memory corruption flaw leading to code execution was reported by security researcher Nils of MWR InfoSecurity during the 2010 Pwn2Own contest sponsored by TippingPoint's Zero Day Initiative. By moving DOM nodes between documents Nils found a case where the moved node incorrectly retained its old scope. If garbage collection could be triggered at the right time then Firefox would later use this freed object.
