NVD Description
Note: Versions mentioned in the description apply only to the upstream keystone package and not the keystone package as distributed by Ubuntu.
The memcache token backend in OpenStack Identity (Keystone) 2013.1 through 2.013.1.4, 2013.2 through 2013.2.2, and icehouse before icehouse-3, when issuing a trust token with impersonation enabled, does not include this token in the trustee's token-index-list, which prevents the token from being invalidated by bulk token revocation and allows the trustee to bypass intended access restrictions.
