wordpress: denial of service in password-protected posts
Last modified: 2013-06-12 05:06:03 EDT
A denial of service vulnerability was reported in WordPress 3.5.1 , 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.
