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. 4. Solution: 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.
