Red Hat Security Advisory

 

Synopsis: Important: openstack-keystone security update

Advisory ID: RHSA-2014:0994-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0994.html

Issue date: 2014-07-31

CVE Names: CVE-2014-3476 CVE-2014-3520

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

 

1. Summary:

 

Updated openstack-keystone packages that fix two security issues are now

available for Red Hat Enterprise Linux OpenStack Platform 3.0 and 4.0.

 

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

Important 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:

 

Red Hat Enterprise Linux OpenStack Platform 3.0 - noarch

Red Hat Enterprise Linux OpenStack Platform 4.0 - noarch

 

3. Description:

 

The OpenStack Identity service (keystone) authenticates and authorizes

OpenStack users by keeping track of users and their permitted activities.

The Identity service supports multiple forms of authentication, including

user name and password credentials, token-based systems, and AWS-style

logins.

 

A flaw was found in keystone's chained delegation. A trustee able to create

a delegation from a trust or an OAuth token could misuse identity

impersonation to bypass the enforced scope, possibly allowing them to

obtain elevated privileges to the trustor's projects and roles.

(CVE-2014-3476)

 

A flaw was found in the way keystone handled trusts. A trustee could use an

out-of-scope project ID to gain unauthorized access to a project if the

trustor had the required roles for that requested project. (CVE-2014-3520)

 

Red Hat would like to thank the OpenStack project for reporting

CVE-2014-3520; upstream acknowledges Jamie Lennox of Red Hat as the

original reporter. The CVE-2014-3476 issue was discovered by Steven Hardy

of Red Hat.

 

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

packages, which correct these issues.
