CVE-2000-1221

Summary

CVE-2000-1221 is a vulnerability affecting the line printer daemon (lpd) in the lpr package of multiple Linux operating systems. Instead of using standard authentication methods, this component authenticates based on the comparison of the reverse-resolved hostname of the local machine to the hostname of the print server. This creates an opportunity for remote attackers to bypass intended access controls by manipulating the DNS records for the attacking IP address, effectively impersonating a trusted print server. This weakness, which was identified in the year 2000, could potentially lead to unauthorized access to the targeted system.
