CRITICAL:
Less critical

IMPACT:

WHERE:
>From remote

SOFTWARE:
Mozilla Firefox 1.x
http://secunia.com/product/4227/

DESCRIPTION:
Secunia Research has discovered a vulnerability in Mozilla, Firefox,
and Camino, which can be exploited by malicious web sites to spoof
dialog boxes.

The problem is that JavaScript dialog boxes do not display or include
their origin, which allows a new window to open e.g. a prompt dialog
box, which appears to be from a trusted site.

Successful exploitation normally requires that a user is tricked into
opening a link from a malicious web site to a trusted web site.

Secunia has constructed a test, which can be used to check if your
browser is affected by this issue:

The vulnerability has been confirmed in Mozilla 1.7.8, FireFox 1.04,
and Camino 0.8.4. Prior versions may also be affected.

SOLUTION:
Do not browse untrusted web sites while browsing trusted sites.
