Upgrade Debian:9 firejail to version 0.9.44.2-3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream firejail package and not the firejail package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
Firejail before 0.9.44.4 and 0.9.38.x LTS before 0.9.38.8 LTS does not consider the .Xauthority case during its attempt to prevent accessing user files with an euid of zero, which allows local users to conduct sandbox-escape attacks via vectors involving a symlink and the --private option.
