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.

Description

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.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
