RHEL 6 : openstack-keystone (RHSA-2014:0089)

critical Nessus Plugin ID 210159

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-2014:0089 advisory.

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 the ec2token API in keystone, which is used to generate EC2-style (Amazon Elastic Compute Cloud) credentials, could generate a token not scoped to a particular trust when creating a token from a received trust-scoped token. A remote attacker could use this flaw to retrieve a token that elevated their privileges to all of the trustor's roles. Note that only OpenStack Identity setups that have EC2-style authentication enabled were affected. (CVE-2013-6391)

Red Hat would like to thank Jeremy Stanley of the OpenStack Project for reporting this issue. Upstream acknowledges Steven Hardy of Red Hat as the original reporter.

These updated packages have been upgraded to upstream version 2013.2.1, which provides a number of bug fixes over the previous version.
(BZ#1045408)

All openstack-keystone users are advised to upgrade to these updated packages, which correct these issues.

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-2014:0089.
