Domain Name Relay Daemon (DNRD) before 2.19.1 allows remote attackers to cause a denial of service (infinite recursion) via a DNS packet that uses message compression in the QNAME and two pointers that point to each other (circular buffer).

Security readout for executives and security teams

CVE-2005-2316 is a denial-of-service flaw in Domain Name Relay Daemon before 2.19.1. A malformed DNS packet can make the daemon recurse indefinitely, potentially disrupting DNS forwarding for users relying on that service. Exposure is limited to systems running DNRD before 2.19.1, especially if the DNS relay is reachable from untrusted networks. The source bundle does not identify affected vendors, packaged distributions, or appliances beyond DNRD itself. Treat as a targeted legacy-service availability risk. Prioritize if DNRD supports production DNS resolution or is reachable externally; otherwise handle through normal legacy software retirement and network hardening. Mitigation focus: Upgrade DNRD to 2.19.1 or later where applicable.; Restrict DNS relay access to trusted networks only.; Disable or replace DNRD if it is no longer required..
