Synopsis
========
Wordpress contains several cross-site scripting, cross-site request
forgery and information leak vulnerabilities.
Background
==========
WordPress is a popular personal publishing platform with a web
interface.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/wordpress <= 2.1.2 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
Description
===========
WordPress contains cross-site scripting or cross-site scripting forgery
vulnerabilities reported by:
* g30rg3_x in the "year" parameter of the wp_title() function
* Alexander Concha in the "demo" parameter of wp-admin/admin.php
* Samenspender and Stefan Friedli in the "post" parameter of
wp-admin/post.php and wp-admin/page.php, in the "cat_ID" parameter of
wp-admin/categories.php and in the "c" parameter of
wp-admin/comment.php
* PsychoGun in the "file" parameter of wp-admin/templates.php
Additionally, WordPress prints the full PHP script paths in some error
messages.
Impact
======
The cross-site scripting vulnerabilities can be triggered to steal
browser session data or cookies. A remote attacker can entice a user to
browse to a specially crafted web page that can trigger the cross-site
request forgery vulnerability and perform arbitrary WordPress actions
with the permissions of the user. Additionally, the path disclosure
vulnerability could help an attacker to perform other attacks.
Workaround
==========
There is no known workaround at this time for all these
vulnerabilities.
Resolution
==========
Due to the numerous recently discovered vulnerabilities in WordPress,
this package has been masked in the portage tree. All WordPress users
are advised to unmerge it.
# emerge --unmerge "www-apps/wordpress"
