Red Hat Security Advisory
Synopsis: Moderate: openstack-keystone security update
Advisory ID: RHSA-2013:1285-01
Product: Red Hat OpenStack
Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1285.html
Issue date: 2013-09-25
CVE Names: CVE-2013-4294
=====================================================================
1. Summary:
Updated openstack-keystone packages that fix one security issue are now
available for Red Hat OpenStack 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.
2. Relevant releases/architectures:
OpenStack 3 - 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 Keystone did not correctly handle revoked PKI tokens,
allowing users with revoked tokens to retain access to resources they
should no longer be able to access. This issue only affected systems using
PKI tokens with the memcache or KVS token back ends. (CVE-2013-4294)
Red Hat would like to thank Thierry Carrez of OpenStack upstream for
reporting this issue. Upstream acknowledges Kieran Spear of University of
Melbourne as the original reporter.
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.
