Title

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

Discussion

Failure to give ownership of the hosts.lpd file to root, bin, sys, or lp provides the designated owner, and possible unauthorized users, with the potential to modify the hosts.lpd file. Unauthorized modifications could disrupt access to local printers from authorized remote hosts or permit unauthorized remote access to local printers.

Check Content

Locate any print service configuration file on the system. Consult vendor documentation to verify the names and locations of print service configuration files on the system. Procedure: # find /etc -name hosts.lpd -print # find /etc -name Systems -print If no print service configuration file is found, this is not applicable. Check the ownership of the print service configuration file(s). Procedure: # ls -lL <print service file> If the owner of the file is not root, sys, bin, or lp, this is a finding.

Fix Text

Change the owner of the /etc/hosts.lpd file (or equivalent, such as /etc/lp/Systems) to root, lp, or another privileged UID. Consult vendor documentation to determine the name and location of print service configuration files. Procedure: # chown root /etc/hosts.lpd
