Synopsis
========
Flaws in WordPress allow a Denial of Service, the disclosure of user
metadata and the overwriting of restricted files.
Background
==========
WordPress is a PHP and MySQL based multiuser blogging system.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/wordpress < 2.0.5 >= 2.0.5
Description
===========
"random" discovered that users can enter serialized objects as strings
in their profiles that will be harmful when unserialized. "adapter"
found out that user-edit.php fails to effectively deny non-permitted
users access to other user's metadata. Additionally, a directory
traversal vulnerability in the wp-db-backup module was discovered.
Impact
======
By entering specially crafted strings in his profile, an attacker can
crash PHP or even the web server running WordPress. Additionally, by
crafting a simple URL, an attacker can read metadata of any other user,
regardless of their own permissions. A user with the permission to use
the database backup plugin can possibly overwrite files he otherwise
has no access to.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All WordPress users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/wordpress-2.0.5"
