Firefox 3.0.8 is a high-priority firedrill security update to Firefox 3.0.x. Due to the pwn2own bug that Nils discovered at CanSecWest 2009 and the XSLT vulnerability recently made public by Guido Landi (www.securityfocus.com/bid/34235) are both critical issues that can result in malicious code execution.
Versions prior to the following are vulnerable:
- Firefox 3.0.8
- SeaMonkey 1.1.16
