Summary
Red Hat Security Advisory: openstack-keystone security, bug fix, and enhancement update

Notes

Topic
Updated openstack-keystone packages that fix two security issues, multiple bugs, and add enhancements are now available for Red Hat OpenStack Essex. The Red Hat Security Response Team has rated this update as having moderate 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.
Details
The openstack-keystone packages provide Keystone, a Python implementation of the OpenStack identity service API, which provides Identity, Token, Catalog, and Policy services. The openstack-keystone packages have been upgraded to upstream version 2012.1.3, which provides a number of bug fixes and enhancements over the previous version. (BZ#867029) This update also fixes the following security issues: It was found that Keystone did not correctly handle users being removed from tenants when Amazon Elastic Compute Cloud (Amazon EC2) style credentials (credentials that are issued in the same format as standard Amazon EC2 credentials) were in use. When a user was removed from a tenant, they retained the privileges provided by that tenant, allowing them to access resources they should no longer have access to. (CVE-2012-5571) When access to Amazon Elastic Compute Cloud (Amazon EC2) was configured, a file permissions flaw in Keystone allowed a local attacker to view the administrative access and secret values used for authenticating requests to Amazon EC2 services. An attacker could use this flaw to access Amazon EC2 and enable, disable, and modify services and settings. (CVE-2012-5483) Red Hat would like to thank the OpenStack project for reporting CVE-2012-5571. Upstream acknowledges Vijaya Erukala as the original reporter of CVE-2012-5571. The CVE-2012-5483 issue was discovered by Kurt Seifried of the Red Hat Security Response Team. All users of openstack-keystone are advised to upgrade to these updated packages, which correct these issues and add these enhancements. After installing the updated packages, the Keystone service (openstack-keystone) will be restarted automatically.
