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 OpenStack Folsom. The Red Hat Security Response Team has rated this update as having important 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 found in the way Keystone handled LDAP (Lightweight Directory Access Protocol) based authentication. If Keystone was configured to use LDAP authentication, and the LDAP server was configured to allow anonymous binds (anonymous binds is a common default), anyone able to connect to a given service using Keystone could connect as any user, including the admin, without supplying a password. (CVE-2013-2157) Red Hat would like to thank Thierry Carrez of OpenStack upstream for reporting this issue. Upstream acknowledges Jose Castro Leon of CERN as the original reporter. All users of openstack-keystone are advised to upgrade to these updated packages, which correct this issue. After installing the updated packages, the Keystone service (openstack-keystone) will be restarted automatically.
