A serious vulnerability in Mozilla Firefox has been addressed in release 2.0.0.7 which is now posted to the Firefox web site. The exploit involved an issue in QuickTime that could reportedly lead to a full compromise of the browser and possibly the underlying operating system. The official Mozilla security blog described the issue as follows:
“If Firefox is the default browser when a user plays a malicious media file handled by QuickTime, an attacker can use a vulnerability in QuickTime to compromise Firefox or the local machine. This can happen while browsing or by opening a malicious media file directly in QuickTime. So far this is only reproducible on Windows.”
