NVD Description

Note: Versions mentioned in the description apply only to the upstream ntp package and not the ntp package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547.
