  - Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer). Supported
    versions that are affected are 5.5.54 and earlier, 5.6.35 and earlier and 5.7.17 and earlier. Easily
    exploitable vulnerability allows low privileged attacker with network access via multiple protocols to
    compromise MySQL Server. While the vulnerability is in MySQL Server, attacks may significantly impact
    additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause
    a hang or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2017-3309)
