Detail

Problem Description:

Updated openstack-keystone packages that fix one security issue and two bugs are now available for Red Hat OpenStack Folsom.

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.

2. Relevant releases/architectures:

OpenStack Folsom - noarch

3. Description:

The openstack-keystone packages provide Keystone, a Python implementation of the OpenStack identity service API, which provides Identity, Token, Catalog, and Policy services.

It was found that an excessive amount of information was logged when invalid tokens were requested, resulting in large log files. An attacker could use this flaw to consume an excessive amount of disk space by requesting a large number of invalid tokens. (CVE-2013-0247)

The CVE-2013-0247 issue was discovered by Dan Prince of Red Hat.

This update also fixes two bugs that could have caused 'keystone' commands (such as 'keystone endpoint-delete' and 'keystone service-get') to fail with a 'No handlers could be found for logger "keystoneclient.v2_0.client"' and 'Authorization Failed' error. (BZ#857290, BZ#888328)

All users of openstack-keystone are advised to upgrade to these updated packages, which correct these issues. After installing the updated packages, the Keystone service (openstack-keystone) will be restarted automatically.

4. Solution:

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

5. Bugs fixed (http://bugzilla.redhat.com/):
