Oracle MySQL 5.1 before 5.1.49 and 5.0 before 5.0.92 allows remote
authenticated users to cause a denial of service (mysqld daemon crash)
by using EXPLAIN with crafted "SELECT ... UNION ... ORDER BY (SELECT
... WHERE ...)" statements, which triggers a NULL pointer dereference
in the Item_singlerow_subselect::store function.
