REDHAT-BUG-628660
First published: Mon Aug 30 2010(Updated: )
A denial of service flaw was found in the way MySQL processed multiple parallel connections changing InnoDB storage engine configuration parameters (innodb_file_format and innodb_file_per_table) and simultaneously issuing data definition language (DDL) statemens. A remote, authenticated MySQL user could use this flaw to cause mysqld daemon abort (assertion failure).
