RHSA-2014:0442 - Security Advisory

Topic

Updated python-keystoneclient 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
Important 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.

Description

Python-keystoneclient is a client library and a command line utility for
interacting with the OpenStack Identity API. The OpenStack Identity
auth_token middleware component handles the authentication of tokens
with keystone.

When using the auth_token middleware with the memcached token cache
enabled, a token for a different identity could be returned. An
authenticated user could use this flaw to escalate their privileges by
making repeated requests that could eventually allow the user to acquire
the administrator's identity. Note that only OpenStack Identity setups
using auth_token with memcached were affected. (CVE-2014-0105)

Red Hat would like to thank the OpenStack project for reporting this issue.
Upstream acknowledges Kieran Spear from the University of Melbourne as the
original reporter.

All python-keystoneclient users are advised to upgrade to these updated
packages, which correct this issue. After installing this update, all
OpenStack services using auth_token must be restarted for this update to
take effect.
