How to fix?

Upgrade SLES:15.0 ntp to version 4.2.8p12-4.3.2 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 SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

Stack-based buffer overflow in ntpq and ntpdc of NTP version 4.2.8p11 allows an attacker to achieve code execution or escalate to higher privileges via a long string as the argument for an IPv4 or IPv6 command-line parameter. NOTE: It is unclear whether there are any common situations in which ntpq or ntpdc is used with a command line from an untrusted source.
