How to fix?

Upgrade Debian:11 ntp to version 1:4.2.6.p5+dfsg-3.2 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.

Multiple stack-based buffer overflows in ntpd in NTP before 4.2.8 allow remote attackers to execute arbitrary code via a crafted packet, related to (1) the crypto_recv function when the Autokey Authentication feature is used, (2) the ctl_putdata function, and (3) the configure function.
