How to fix?

Upgrade Debian:9 cups to version 2.2.1-8+deb9u2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cups package and not the cups package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

The CUPS AppArmor profile incorrectly confined the dnssd backend due to use of hard links. A local attacker could possibly use this issue to escape confinement. This flaw affects versions prior to 2.2.7-1ubuntu2.1 in Ubuntu 18.04 LTS, prior to 2.2.4-7ubuntu3.1 in Ubuntu 17.10, prior to 2.1.3-4ubuntu0.5 in Ubuntu 16.04 LTS, and prior to 1.7.2-0ubuntu1.10 in Ubuntu 14.04 LTS.
