Descriptions

NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service (prevent communication with a source) by sending a response for a source to an interface the source does not use.

NTP en versiones anteriores a 4.2.8p9 cambia la estructura de los pares a la interfaz que recibe la respuesta de una fuente, lo que permite a atacantes remotos provocar una denegaciĆ³n de servicio (prevenir la comunicaciĆ³n con una fuente) enviando una respuesta para una fuente a una interfaz que la fuente no utiliza.

A flaw was found in the way ntpd running on a host with multiple network interfaces handled certain server responses. A remote attacker could use this flaw which would cause ntpd to not synchronize with the source.
