It was discovered that the PolicyKit pkexec tool incorrectly handled command-line arguments.
A local attacker could use this issue to escalate privileges to an administrator.
Policykit is a part of systemd daemon
It is not used by Artica.
If you using Artica ISO or Artica Virtual appliances, systemd is removed by default and the binary /usr/bin/pkexec is no longer on the system.
If you have installed Artica manually on your own Debian system, check the presence of the /usr/bin/pkexec.
If exists, do a chmod 0755 /usr/bin/pkexec and/or upgrade your operating system.
