WordPress is a PHP and MySQL based multiuser blogging system.
"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 type="normal">
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.
There is no known workaround at this time.
All WordPress users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-apps/wordpress-2.0.5&quot;</code>
