RHEL 6 : openstack-keystone (RHSA-2013:0994)

critical Nessus Plugin ID 193678

Synopsis

The remote Red Hat host is missing a security update for openstack-keystone.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0994 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL openstack-keystone package based on the guidance in RHSA-2013:0994.
