Red Hat Security Advisory

 

Synopsis: Moderate: openstack-keystone security, bug fix, and enhancement update

Advisory ID: RHSA-2012:1556-01

Product: Red Hat OpenStack

Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1556.html

Issue date: 2012-12-10

CVE Names: CVE-2012-5483 CVE-2012-5571

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

 

1. Summary:

 

Updated openstack-keystone packages that fix two security issues, multiple

bugs, and add enhancements are now available for Red Hat OpenStack Es[censored].

 

The Red Hat Security Response Team has rated this update as having moderate

security impact. Common Vulnerability Scoring System (CVSS) base scores,

which give detailed severity ratings, are available for each vulnerability

from the CVE links in the References section.

 

2. Relevant releases/architectures:

 

RHOS Es[censored] Release - 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.

 

The openstack-keystone packages have been upgraded to upstream version

2012.1.3, which provides a number of bug fixes and enhancements over the

previous version. (BZ#867029)

 

This update also fixes the following security issues:

 

It was found that Keystone did not correctly handle users being removed

from tenants when Amazon Elastic Compute Cloud (Amazon EC2) style

credentials (credentials that are issued in the same format as standard

Amazon EC2 credentials) were in use. When a user was removed from a tenant,

they retained the privileges provided by that tenant, allowing them to

access resources they should no longer have access to. (CVE-2012-5571)

 

When access to Amazon Elastic Compute Cloud (Amazon EC2) was configured,

a file permissions flaw in Keystone allowed a local attacker to view the

administrative access and secret values used for authenticating requests to

Amazon EC2 services. An attacker could use this flaw to access Amazon EC2

and enable, disable, and modify services and settings. (CVE-2012-5483)

 

Red Hat would like to thank the OpenStack project for reporting

CVE-2012-5571. Upstream acknowledges Vijaya Erukala as the original

reporter of CVE-2012-5571. The CVE-2012-5483 issue was discovered by Kurt

Seifried of the Red Hat Security Response Team.

 

All users of openstack-keystone are advised to upgrade to these updated

packages, which correct these issues and add these enhancements. After

installing the updated packages, the Keystone service (openstack-keystone)

will be restarted automatically.
