Firefox 3.6.3 Released. Update Now!

The Mozilla developers have just released Firefox 3.6.3, an update to the latest version of the Firefox web browser. This update fixes a critical security vulnerability in Firefox 3.6.2 making it a recommended update for all uses who have that version of the web browser installed. The critical security vulnerability could allow remote code execution and was reported by Nils of MWR InfoSecurity who won the Pwn2Own 2010 Firefox price money for exploiting the web browser with that vulnerability.

A memory corruption flaw leading to code execution was reported by security researcher Nils [..] 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.

The exploit is only affecting Firefox 3.6 versions which means that users who are still running Firefox 3.6 or Firefox 3.6.1 should also update their version to the latest immediately.

Firefox 3.6.3 is already available via the browser’s automatic update check which is the most comfortable option to update the web browser. The download is also provided on the Mozilla website for users who want to download the setup files to their computer system first.
