SV-35143r1: The hosts.lpd (or equivalent) file must be owned by root, bin, sys, or lp. | HP-UX 11.31 Security Technical Implementation Guide

Assessment Title

Rule Text

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

Description

Discussion Text

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.

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

Remediation

Change the owner of the /etc/hosts.lpd file (or equivalent) to root, lp, or another privileged UID. 
# chown root <print service configuration file>
