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 ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename.
