References: [1] http://secunia.com/advisories/41048/ [2] http://dev.mysql.com/doc/refman/5.1/en/news-5-1-49.html Upstream bug report: [3] http://bugs.mysql.com/bug.php?id=54044 Note: This issue only causes a temporary denial of service, as the mysql daemon shipped with Red Hat Enterprise Linux 5 will be automatically restarted after the abort.
Public reproducer (from [3]): SET storage_engine=innodb; CREATE TEMPORARY TABLE mk_upgrade AS SELECT IF(NULL IS NOT NULL, NULL , NULL) ; drop table mk_upgrade;
