How to fix?

Upgrade Debian:11 ntp to version 4.0 or higher.

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.

Integer overflow in the NTP daemon (NTPd) before 4.0 causes the NTP server to return the wrong date/time offset when a client requests a date/time that is more than 34 years away from the server's time.
