mysql is vulnerable to authorization bypass. The vulnerability exists through multiple format string flaws were found in the way the MySQL server logs user commands when creating and deleting databases. A remote, authenticated attacker with permissions to CREATE and DROP databases could use these flaws to formulate a specifically-crafted SQL command that would cause a temporary denial of service (open connections to mysqld are terminated).
