CVE-2007-6304 (The federated engine in MySQL 5.0.x before 5.0.52, 5.1.x before 5.1.23, and 6.0.x before 6.0.4, when performing a certain SHOW TABLE STATUS query, does not properly handle a response with a small number of columns, which allows remote MySQL servers to cause a denial of service (federated handler crash and daemon crash) via a response that lacks the minimum required number of columns.)
