The remote Red Hat host is missing one or more security updates.
Updated python-keystoneclient packages that fix one security issue are
now available for Red Hat Storage 2.1.
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.
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. The gluster-swift component, provided by Red Hat
Storage, requires the auth_token middleware.
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.
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.
The python-keystoneclient package has been upgraded to version 0.7.1.
Additionally, the python-six package has been upgraded to version
1.5.2, as required by the updated python-keystoneclient package.
All python-keystoneclient users are advised to upgrade to these
updated packages, which correct this issue. After installing this
update, the gluster-swift proxy, or any other services using
auth_token, must be restarted for this update to take effect.
