Firefox Update Patch 9 Security Vulnberabilities, 4 Rated Critical

Mozilla has released a new version of its Firefox browser that plugs nine security holes, four of which are rated “critical,” the foundation’s highest vulnerability level.

Version 3.0.11 squashes a javascript chrome privilege escalation bug, which Mozilla said allows attackers to execute malware on the computers of end users. Exploits would work by manipulating chrome privileged objects, such as a browser sidebar.

Other critical vulnerabilities include stability bugs in the browser engine, crashes that caused memory corruption and a race condition while accessing the private data of a NPObject JS wrapper class object. A complete list of fixes is available here.

Mozilla said some of same bugs have been fixed in version 2.0.0.22 of Thunderbird, but at time of writing, the most current version of the email application was 2.0.0.21. We wouldn’t be surprised if an update was released soon.

As usual, the update will be pushed directly to Firefox users and requires only a simple restart of the browser to be installed.
