TITLE:
Firefox Property Manipulation Cross-Site Scripting Vulnerability

SECUNIA ADVISORY ID:
SA15549

VERIFY ADVISORY:
http://secunia.com/advisories/15549/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
From remote

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

DESCRIPTION:
Secunia Research has discovered a vulnerability in Firefox, which can
be exploited by malicious people to conduct cross-site scripting
attacks.

The problem is that the "frames", "parent", "self", and "top" DHTML
properties are not properly protected from being modified by another
site via JavaScript. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an
arbitrary site, which calls a method in one of the modified
properties.

The vulnerability has been confirmed in version 1.0.4. Prior versions
may also be affected.

SOLUTION:
Update to version 1.0.5.
