CVE-2009-4019 is an error-handling flaw in mysqld affecting MySQL 5.0 releases before 5.0.88 and 5.1 releases before 5.1.41. mysqld improperly handles errors from certain SELECT statements containing subqueries, including SELECT statements with a subquery in a WHERE clause that assigns a result to a user variable. It also fails to preserve certain null_value flags while processing statements using the GeomFromWKB function. A remote authenticated user can submit a crafted SQL statement that causes mysqld to crash.
