The OpenStack Identity\nauth_token middleware component handles the authentication of tokens\nwith keystone.\n\nWhen using the auth_token middleware with the memcached token cache\nenabled, a token for a different identity could be returned. An\nauthenticated user could use this flaw to escalate their privileges by\nmaking repeated requests that could eventually allow the user to acquire\nthe administrator's identity. Note that only OpenStack Identity setups\nusing auth_token with memcached were affected. (CVE-2014-0105)\n\nRed Hat would like to thank the OpenStack project for reporting this issue.\nUpstream acknowledges Kieran Spear from the University of Melbourne as the\noriginal reporter.\n\nThe python-keystoneclient package has been upgraded to version 0.7.1.\nAdditionally, the python-six package has been upgraded to version 1.5.2,\nrequired by the updated python-keystoneclient package.\n\nAll python-keystoneclient users are advised to upgrade to these updated\npackages, which correct this issue. After installing this update, all\nOpenStack services using auth_token must be restarted for this update to\ntake effect.",
