Descriptions
The process_tgs_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.9 through 1.9.2 allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS request that triggers an error other than the KRB5_KDB_NOENTRY error.
La función process_tgs_req en do_tgs_req.c en Key Distribution Center (KDC) en MIT Kerberos 5 (también conocido como krb5) v1.9 hasta v1.9.2 permite a usuarios autenticados remotamente provocar una denegación de servicio (desreferencia a puntero nulo y caída del demonio) a través de una petición TGS modificada que provoca un error diferente del error KRB5_KDB_NOENTRY.
