Security Advisory Moderate: openstack-keystone security update

Advisory: RHSA-2014:0113-1
Type: Security Advisory
Severity: Moderate
Issued on: 2014-01-30
Last updated on: 2014-01-30
Affected Products: Red Hat OpenStack 3.0
CVEs ( CVE-2013-4477


Updated openstack-keystone packages that fix one security issue are now
available for Red Hat Enterprise Linux OpenStack Platform 3.0.

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

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 discovered in the way the LDAP backend in keystone handled the
removal of a role. A user could unintentionally be granted a role if the
role being removed had not been previously granted to that user. Note that
only OpenStack Identity setups using an LDAP backend were affected.

All openstack-keystone users are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue.


Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
