This vulnerability allows the attacker to predict a DNS query's source port in order to send forged DNS response packets that will be accepted as valid answers to the DNS client's requests (without sniffing the specific request). Data is predictable because it is based on the time of day, and has too few bits."

Esta vulnerabilidad permite al atacante predecir el puerto de origen de una consulta DNS para enviar paquetes de respuesta DNS falsos que ser\u00e1n aceptados como respuestas v\u00e1lidas a las peticiones del cliente DNS (sin olfatear la petici\u00f3n espec\u00edfica). Los datos son predecibles porque son basados en la hora del d\u00eda y presentan muy pocos bits."
