Check Text ( C-36128r2_chk )
Check the permissions of the /etc/cups/printers.conf file.

# ls -lL /etc/cups/printers.conf

If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.


Fix Text (F-31372r1_fix)
Remove the extended ACL from the file.
# setfacl --remove-all /etc/cups/printers.conf
