Summary
Red Hat Security Advisory: openstack-keystone security update

Notes

Topic
Updated openstack-keystone packages that fix one security issue are now available for Red Hat Enterprise Linux OpenStack Platform 3.0. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Details
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. (CVE-2013-4477) All openstack-keystone users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
