Red Hat Security Advisory

 

Synopsis: Important: openstack-keystone security and bug fix update

Advisory ID: RHSA-2013:0994-01

Product: Red Hat OpenStack

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0994.html

Issue date: 2013-06-27

CVE Names: CVE-2013-2157

=====================================================================

 

1. Summary:

 

Updated openstack-keystone packages that fix one security issue and various

bugs are now available for Red Hat OpenStack 3.0 (Grizzly) Preview.

 

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.

 

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.

 

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.

 

These updated packages have been upgraded to upstream version 2013.1.2,

which provides a number of bug fixes over the previous version. (BZ#972660)

 

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.
