Description:
Michal Zalewski has discovered a weakness in Firefox, which can be exploited by malicious people to conduct phishing attacks.

The weakness is caused due to Firefox allowing scripts to open a tab with a blank address bar and add arbitrary content to it. This can further be exploited to spoof the user interface, including setting the title to an arbitrary value.

The weakness is confirmed in version 2.0.0.1. Other versions may also be affected.

Solution:
Update to version 2.0.0.4 or later.
