OpenStack Keystone 2012.1.3 does not invalidate existing tokens when
granting or revoking roles, which allows remote authenticated users to
retain the privileges of the revoked roles.
Dolph Mathews discovered that when roles are granted and revoked to
users in Keystone, pre-existing tokens were not updated or invalidated
to take the new roles into account. An attacker could use this to
continue to access resources that have been revoked.
