Description
The issue is related to the InnoDB component of MySQL Server, allowing a high-privileged attacker with network access via multiple protocols to compromise the server. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. The vulnerability is easily exploitable and can be triggered remotely using the MySQL network protocol.
