Descriptions

ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file.

ntpd en ntp versión 4.2.8 versiones anteriores a 4.2.8p15 y versiones 4.3.x anteriores a 4.3.101, permite a atacantes remotos causar una denegación de servicio (consumo de la memoria) mediante el envío de paquetes, porque la memoria no es liberada en situaciones donde se usa una clave CMAC y está asociada con un algoritmo CMAC en el archivo ntp.keys
