Security researchers announced a new vulnerability for users of the Firefox 1.0.6 browsers on a Unix or Linux platform. The problem revolves around a security bug that could allow hackers to execute arbitrary shell commands if they can trick the user into accepting a malicious link on a website.

The problem has been confirmed with RedHat Linux / Fedora Core 4, and Mozilla Firefox version 1.0.6. Users of Firefox on these systems are encouraged to upgrade to Firefox 1.0.7
