CVE-2011-1966

Estado: ModificadaAlta (10)—

El servidor DNS de Microsoft Windows Server 2008 SP2, R2, y R2 SP1 no maneja apropiadamente peticiones NAPTR lo que provoca un procesamiento recursivo, lo que permite a atacantes remotos ejecutar código arbitrario a través de una petición modificada. También conocida como "vulnerabilidad de petición DNS NAPTR".
