There was a remote code execution vulnerability for Mozilla Firefox 3 discovered last month.

We mentioned it in our June 19th post.

Version 3.0.1 has been released to resolve MFSA2008-34 and two other security issues. But the nice thing about Firefox is that you probably already know about the fix if you have the "automatically check for updates" option selected.



For more details see the Firefox 3.0.1 Release Notes or Mozilla Foundation Security Advisory 2008-34.
