Descriptions

NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service (stack exhaustion) via an ntpdc relist command, which triggers recursive traversal of the restriction list.

NTP en versiones anteriores a 4.2.8p6 y 4.3.0 en versiones anteriores a 4.3.90 permite a atacantes remotos provocar una denegación de servicio (agotamiento de la pila) a través de un comando ntpdc relist, lo que desencadena el recorrido recursivo de la lista de restricciones.

A stack-based buffer overflow flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could use this flaw to crash ntpd.
