Descriptions

ntp_request.c in ntpd in NTP before 4.2.4p8, and 4.2.5, allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by using MODE_PRIVATE to send a spoofed (1) request or (2) response packet that triggers a continuous exchange of MODE_PRIVATE error responses between two NTP daemons.

ntp_request.c en ntpd en NTP anterior v4.2.4p8, y v4.2.5, permite a atacantes remotos causar una denegación de servicio (consumo de CPU y ancho de banda) por uso de MODE_PRIVATE para enviar una suplantación de (1) petición o (2) paquete respueta lo que lanza continuo intercambio de errores de respuesta MODE_PRIVATE entre dos demonios NTP.
