Descriptions
ntpd in ntp 4.2.8p10, 4.2.8p11, 4.2.8p12 and 4.2.8p13 allow remote attackers to prevent a broadcast client from synchronizing its clock with a broadcast NTP server via soofed mode 3 and mode 5 packets. The attacker must either be a part of the same broadcast network or control a slave in that broadcast network that can capture certain required packets on the attacker's behalf and send them to the attacker.
ntpd en ntp versiones 4.2.8p10, 4.2.8p11, 4.2.8p12 y 4.2.8p13, permiten a atacantes remotos impedir que un cliente de multidifusión sincronice su reloj con un servidor NTP de multidifusión por medio de paquetes de modo 3 y modo 5 suplantados. El atacante debe ser parte de la misma red de multidifusión o controlar un esclavo en esa red de multidifusión que puede capturar determinados paquetes requeridos en nombre del atacante y enviarlos luego al atacante.
