Descriptions

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.

El memcache token backend en OpenStack Identity (Keystone) 2013.1 hasta 2.013.1.4, 2013.2 hasta 2013.2.2 y icehouse anterior a icehouse-3, cuando se emite un token de confianza con suplantaciĆ³n habilitada, no incluye este token en la lista de indice de tokens del trustee, lo que previene el token ser invalidado por la revocaciĆ³n de tokens en masa y permite al trustee evadir restricciones de acceso.
