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" References ========== [ 1 ] CVE-2006-5705 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5705 [ 2 ] WordPress Ticket 3142 http://trac.wordpress.org/ticket/3142 [ 3 ] WordPress Ticket 2591 http://trac.wordpress.org/ticket/2591 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200611-10.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
