Synopsis
========

Gallery is vulnerable to cross-site scripting attacks.

Background
==========

Gallery is a web application written in PHP which is used to organize
and publish photo albums. It allows multiple users to build and
maintain their own albums. It also supports the mirroring of images on
other servers.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /   Vulnerable   /                   Unaffected
    -------------------------------------------------------------------
  1  www-apps/gallery      <= 1.4.4_p4                     >= 1.4.4_p5

Description
===========

Rafel Ivgi has discovered a cross-site scripting vulnerability where
the 'username' parameter is not properly sanitized in
 'login.php'.

Impact
======

By sending a carefully crafted URL, an attacker can inject and execute
script code in the victim's browser window, and potentially compromise
the user's gallery.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Gallery users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/gallery-1.4.4_p5"
