Red Hat Security Advisory 2014-0113-01 - The openstack-keystone packages provide keystone, a Python implementation of the OpenStack Identity service API, which provides Identity, Token, Catalog, and Policy services. A flaw was discovered in the way the LDAP backend in keystone handled the removal of a role. A user could unintentionally be granted a role if the role being removed had not been previously granted to that user. Note that only OpenStack Identity setups using an LDAP backend were affected. All openstack-keystone users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
