Title

The hosts.lpd (or equivalent) must have mode 0644 or less permissive. (Cat II impact)

Discussion

Excessive permissions on the hosts.lpd (or equivalent) file may permit unauthorized modification. 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 for the name and location of print service configuration files. Procedure: # find /etc -name hosts.lpd -print # find /etc -name Systems –print # find /etc -name printers.conf -print Check the mode of the print service configuration file. # ls -lL <print service file> If no print service configuration file is found, this is not applicable. If the mode of the print service configuration file is more permissive than 0644, this is a finding.

Fix Text

Change the mode of the /etc/hosts.lpd file (or equivalent, such as /etc/lp/Systems) to 0644 or less permissive. Consult vendor documentation for the name and location of print service configuration files. Procedure: # chmod 0644 <print service file>
