A flaw in MySQL versions prior to 5.1.51 [1] was reported [2] that could allow an authenticated user to kill connections to MySQL. A user-variable assignment expression that is evaluated in a logical expression context can be precalculated in a temporary table for GROUP BY. However, when the expression value is used after creation of the temporary table, it was re-evaluated, not read from the table and a server crash resulted.
