Description Vincent Danen 2013-06-11 20:18:43 UTC
A denial of service vulnerability was reported in WordPress 3.5.1 [1],[2] that could allow a remote unauthenticated user to exhaust CPU and memory resources by sending an HTTP request with a specially-crafted password cookie to a WordPress URL of a password-protected post.  This vulnerability is caused by an error when calculating the hash cycle count within the crypt_private() method in wp-includes/class-phpass.php.There is currently no upstream fix for this, and it requires the attacker to have knowledge of a WordPress site's password-protected post URL, if there is one.
