Buffer overflow in the mysql_real_connect function in MySQL 4.x before 4.0.21, and 3.x before 3.23.49, allows remote DNS servers to cause a denial of service and possibly execute arbitrary code via a DNS response with a large address length (h_length).

Security readout for executives and security teams

This is an old MySQL client-side buffer overflow. A malicious or compromised DNS server could return an oversized address length and crash vulnerable MySQL clients, with possible code execution. The business risk is mainly legacy estate exposure, not modern supported MySQL deployments. Exposure is most likely in legacy applications or systems using affected MySQL 3.x or 4.x client libraries, especially where hostnames are resolved through untrusted, spoofable, or compromised DNS paths. Treat this as a legacy-risk cleanup item with high impact if affected systems remain. Prioritize internet-facing or business-critical applications that still use old MySQL client libraries. Mitigation focus: Upgrade MySQL 4.x to 4.0.21 or later.; Upgrade MySQL 3.x to 3.23.49 or later.; Apply fixed distribution packages from relevant vendor advisories..
