Synopsis
========

WordPress contains HTTP response splitting and cross-site scripting
vulnerabilities.

Background
==========

WordPress is a PHP and MySQL based content management and publishing
system.

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  www-apps/wordpress       < 1.2.1                         >= 1.2.1

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

Due to the lack of input validation in the administration panel
scripts, WordPress is vulnerable to HTTP response splitting and
cross-site scripting attacks.

Impact
======

A malicious user could inject arbitrary response data, leading to
content spoofing, web cache poisoning and other cross-site scripting or
HTTP response splitting attacks. This could result in compromising the
victim's data or browser.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All WordPress users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=www-apps/wordpress-1.2.1"
    # emerge ">=www-apps/wordpress-1.2.1"
