Title

The hosts.lpd (or equivalent) file must be group-owned by root, bin, or sys. (Cat II impact)

Discussion

Failure to give group ownership of the hosts.lpd (or equivalent) file to root, bin, sys, or system provides the members of the owning group and possible unauthorized users, with the potential to modify it. Unauthorized modifications could disrupt access to local printers from authorized remote hosts or permit unauthorized remote access to local printers.

Check Content

Check the group ownership of the print service configuration files. Procedure: # ls -lL /etc/printers.conf /etc/apache/httpd-standalone-ipp.conf /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf If the files are not group-owned by root, bin, or sys, this is a finding.

Fix Text

Change the group owner of the print service configuration files. Procedure: # chgrp bin /etc/apache/httpd-standalone-ipp.conf # chgrp root /etc/printers.conf /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf
