<background>
<p>
WordPress is a PHP and MySQL based multiuser blogging system.

<p>
"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.
</p>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All WordPress users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-apps/wordpress-2.0.5&quot;</code>
</resolution>
