A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions."

Un atacante autenticado y remoto puede hacer que el proceso winbindd se bloquee usando un ticket de Kerberos leg\u00edtimo.
