Description Vincent Danen 2010-10-06 20:34:53 UTC
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.
