CVE-2004-0836
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).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.80%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
