Upgrade Debian:10 file to version 1:5.17-0.1 or higher.

NVD Description

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

The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters.
