Synopsis
========

MediaWiki is vulnerable to a cross-site scripting attack that could
allow arbitrary scripting code execution.

Background
==========

MediaWiki is a collaborative editing software, used by big projects
like Wikipedia.

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

     -------------------------------------------------------------------
      Package             /  Vulnerable  /                   Unaffected

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

MediaWiki incorrectly handles page template inclusions, rendering it
vulnerable to cross-site scripting attacks.

Impact
======

A remote attacker could exploit this vulnerability to inject malicious
script code that will be executed in a user's browser session in the
context of the vulnerable site.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MediaWiki users should upgrade to the latest available versions:

     # emerge --sync
     # emerge --ask --oneshot --verbose www-apps/mediawiki
