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 secure authentication methods, this software compares the reverse-resolved hostname of the local machine with the hostname of the print server. A remote attacker can exploit this flaw by manipulating the DNS records for the attacking IP, enabling them to bypass intended access controls and potentially gain unauthorized access to the system. This issue highlights the importance of secure authentication and proper handling of DNS records to prevent unintended consequences.
