How to fix?

Upgrade Debian:10 maradns to version 1.4.03-1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream maradns package and not the maradns package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

The compress_add_dlabel_points function in dns/Compress.c in MaraDNS 1.4.03, 1.4.05, and probably other versions allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a long DNS hostname with a large number of labels, which triggers a heap-based buffer overflow.
