Description Tomas Hoger 2007-12-11 13:03:33 EST
Common Vulnerabilities and Exposures assigned an identifier CVE-2007-6304 to the following vulnerability:

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.

Comment 1 Tom Lane 2007-12-11 15:42:48 EST
This one is a non-issue for us, because we don't enable the federated storage engine.
Comment 2 Tomas Hoger 2007-12-12 04:17:58 EST
Red Hat Enterprise Linux and Fedora mysql packages are not affected by this issue.

MySQL versions as shipped in Red Hat Enterprise Linux 2.1, 3, and 4 do not
support federated storage engine at all.  MySQL packages as shipped in Red Hat
Enterprise Linux 5 and Fedora are not compiled with support for federated
storage engine.
