Description Jan Lieskovsky 2013-03-05 09:59:12 EST
A denial of service flaw was found in the way ruby-openid, a library for verifying and serving OpenID identities, performed processing of certain XML files. An OpenID provider could provide a specially-crafted XML file that, when processed would lead to excessive CPU consumption (denial of service).
