Red Hat Security Advisory
Synopsis: Moderate: openstack-keystone security and bug fix update
Advisory ID: RHSA-2013:1524-01
Product: Red Hat OpenStack
Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1524.html
Issue date: 2013-11-18
CVE Names: CVE-2013-4222
Updated openstack-keystone packages that fix one security issue and several
bugs 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
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 tokens issued to a tenant were not invalidated when that
tenant was disabled in Keystone. This could allow users assigned to a
disabled tenant to retain access to resources they should no longer be able
to access. (CVE-2013-4222)
These updated packages have been upgraded to upstream version 2013.1.4,
which provides a number of bug fixes over the previous version.
This update also fixes the following bug:
* WebOb 1.0 has been removed from the Red Hat Openstack 3.0 package
requirements; all packages now use WebOb 1.2.3. (BZ#1012694)
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
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

995598 - CVE-2013-4222 OpenStack: Keystone disabling a tenant does not disable a user token
