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:11 relevant fixed versions and status.
The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash). NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750.
