How to fix?

Upgrade Debian:10 dpkg to version 1.17.22 or higher.

NVD Description

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

Multiple format string vulnerabilities in the parse_error_msg function in parsehelp.c in dpkg before 1.17.22 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in the (1) package or (2) architecture name.
