Vulnerability Note VU#349217

Original Release Date: 2007-10-19 | Last Revised: 2007-10-19

Overview

Mozilla's XUL contains a vulnerability that may allow a web application to cover an active window's titlebar.

Description

XUL is Mozilla's XML-based user interface language. XUL can be used to create Mozilla applications, extensions, and web applications.

From Mozilla Foundation Security Advisory 2007-33:
Mozilla developer Eli Friedman discovered that web pages written in the XUL markup language (rather than the usual HTML) can hide their window's titlebar. It may have been possible to abuse this ablity to create more convincing spoof and phishing pages.

Solution

Upgrade

Mozilla has released Firefox 2.0.0.8 and SeaMonkey 1.1.5 to address this issue.
