Firefox users: Upgrade now to fix critical security vulnerability

If you have users who use Firefox as their web browser, they need to be upgraded to the latest version (3.6.2), which addresses a critical security vulnerability that can allow an attacker to crash the machine or execute arbitrary code. This applies to those running Firefox 3.6 and doesn't affect earlier versions. The technology involved is Web Open Font Format (WOFF). Mozilla released 3.6.2 ahead of schedule after the German CERT recommended that users stop using Firefox until the patch was released.
