Red Hat Security Advisory 2013-0596-01 – The openstack-keystone packages provide Keystone, a Python implementation of the OpenStack identity service API, which provides Identity, Token, Catalog, and Policy services. The openstack-keystone packages have been upgraded to upstream version 2012.2.3, which provides a number of bug fixes and enhancements over the previous version. This update also fixes the following security issues: It was found that Keystone failed to properly validate disabled user accounts, or user accounts associated with disabled tenants or domains, when Amazon Elastic Compute Cloud style credentials were in use. Such users could use this flaw to access resources they should no longer have access to.
