CVE-2020-11868 Open this link in a new tabHow to fix?
Upgrade Debian:11 ntp to version 1:4.2.8p14+dfsg-1 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.
ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp.
