Description Jan Lieskovsky 2013-06-11 14:47:34 UTC

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.
