DESCRIPTION:
Michal Zalewski has discovered a vulnerability in Mozilla Firefox,
which can be exploited by malicious people to conduct spoofing
attacks.

The vulnerability is caused due to the address bar of a newly opened
window displaying the URL of the requested location before the page
is loaded. This can be exploited to display arbitrary content in the
blank document while showing the URL of a trusted web site in the
address bar, e.g. by calling "window.stop()" to abort loading the new
page.

The vulnerability is confirmed in version 3.6.4. Other versions may
also be affected.

SOLUTION:
Do not rely on the address bar when untrusted web sites open new
windows.
