Descriptions

An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. A specially crafted unauthenticated network packet can be used to reset the expected origin timestamp for target peers. Legitimate replies from targeted peers will fail the origin timestamp check (TEST2) causing the reply to be dropped and creating a denial of service condition.

Existe una vulnerabilidad explotable de denegación de servicio (DoS) en la funcionalidad de comprobación de marca de tiempo de origen de ntpd 4.2.8p9. Se puede emplear un paquete de red no autenticado especialmente manipulado para reiniciar la marca de tiempo de origen esperada para los peers objetivo. Las respuestas legítimas de los peers objetivo no pasarán la comprobación de marca de tiempo de origen (TEST2), lo que hace que la respuesta se elimine y se cree una condición de denegación de servicio (DoS).
