  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 5.7.34 and prior and 8.0.25 and prior. Difficult to exploit vulnerability allows high
    privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful
    attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable
    crash (complete DOS) of MySQL Server. (CVE-2021-2372)
