Red Hat Security Advisory


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

Advisory ID: RHSA-2014:1121-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1121.html

Issue date: 2014-09-02

CVE Names: CVE-2014-5251 CVE-2014-5252 CVE-2014-5253



1. Summary:


Updated openstack-keystone packages that fix three security issues and

several bugs are now available for Red Hat Enterprise Linux OpenStack

Platform 5.0 for Red Hat Enterprise Linux 7.


Red Hat Product Security has rated this update as having Low 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:


OpenStack 5.0 for RHEL 7 - 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



It was found that the MySQL token driver did not correctly store token

expiration times, which prevented manual token revocation. Only OpenStack

Identity setups configured to make use of revocation events were affected.



A flaw was found in keystone revocation events that resulted in the

"issued_at" time being updated when a token created by the V2 API was

processed by the V3 API. This could allow a user to evade token revocation.

Only OpenStack Identity setups configured to make use of revocation events

and UUID tokens were affected. (CVE-2014-5252)


It was discovered that domain-scoped tokens were not revoked when a domain

was disabled. Only OpenStack Identity setups configured to make use of

revocation events were affected. (CVE-2014-5253)


The openstack-keystone packages have been upgraded to upstream version

2014.1.2.1, which provides a number of bug fixes over the previous version.

The most notable bug fixes are:


* When a scoped token that was created from an unscoped token was revoked,

the original token was revoked as well. This was because the scope was not

included in the revocation event. By including the scope in the revocation

event, only the scoped token is revoked.


* If a domain or a project was renamed, the old name remained in the cache.

As a result the old name could be used in some requests until the cache

record expired. For example, the old domain name could still be used for

authentication after renaming the domain. Cache entries are now properly

invalidated for domain and project rename operations.


* OpenStack Identity did not return the same status and headers for HEAD

and GET requests, which does not follow the HTTP specification. This would

lead to different status codes between running keystone-all versus running

keystone in Apache httpd with mod_wsgi. The responses have been corrected

to be consistent regardless of the webserver being used.


* The migration operation that creates the region table did not explicitly

set the character set to 'utf8'. Consequently, when the database's default

character set was not set, the db_sync operation failed. The migration

operation now detects this condition and corrects the database.


Refer to https://launchpad.net/keystone/icehouse/2014.1.2 for more

information on the bug fixes included in version 2014.1.2.1. (BZ#1127434)


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

packages, which correct these issues.

relevant to your system have been applied.
