Topic

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.

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.
