The line printer daemon (lpd) in the lpr package in multiple Linux operating systems authenticates by comparing the reverse-resolved hostname of the local machine to the hostname of the print server as returned by gethostname, which allows remote attackers to bypass intended access controls by modifying the DNS for the attacking IP.

Security readout for executives and security teams

This is an old flaw in Linux lpd printing software. It trusted DNS names for access decisions, so an attacker controlling DNS for their own IP could appear trusted and bypass print-server controls. Exposure is most likely on legacy Linux systems still running affected lpr/lpd packages or inherited systems with lpd enabled. The bundle does not identify exact supported product versions or CPEs. Prioritize discovery of legacy lpd exposure. Modern fleets may have little exposure, but unmaintained print servers can create avoidable remote access-control risk. Mitigation focus: Apply relevant vendor lpr/lpd updates from historical or current operating-system guidance.; Disable lpd where network printing is not required.; Restrict access to trusted administrative or print-client networks..
