Description

<em style='font-weight:bold;'>(Description Provided by <a href="http://cve.mitre.org/cgi-bin/cvename.cgi?name=2010-3835" target="_blank">CVE</a>)</em> : MySQL 5.1 before 5.1.51 and 5.5 before 5.5.6 allows remote authenticated users to cause a denial of service (mysqld server crash) by performing a user-variable assignment in a logical expression that is calculated and stored in a temporary table for GROUP BY, then causing the expression value to be used after the table is created, which causes the expression to be re-evaluated instead of accessing its value from the table.
