Red Hat Security Advisory 2012-1556-01 - 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 2012.1.3, 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 did not correctly handle users being removed from tenants when Amazon Elastic Compute Cloud style credentials were in use. When a user was removed from a tenant, they retained the privileges provided by that tenant, allowing them to access resources they should no longer have access to.
