RHSA-2013:0253 - Security Advisory

Topic

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.

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.
