Description Jan Lieskovsky 2013-06-11 10:47:34 EDT
A denial of service flaw was found in the way Wordpress, a blog tool and publishing platform, performed hash computation when checking password for password protected blog posts. A remote attacker could provide a specially-crafted input that, when processed by the password checking mechanism of Wordpress would lead to excessive CPU consumption.

This issue affects the versions of the wordpress package, as shipped with Fedora release of 17, 18, Fedora EPEL-5 and Fedora EPEL-6. Please schedule an update (once there is final upstream patch available [should upstream confirm the patch proposal as working or come with own one]).
