Vulnerability in the MySQL Server component of Oracle MySQL
(subcomponent: Server: Storage Engines). Supported versions that are
affected are 5.5.61 and prior, 5.6.41 and prior, 5.7.23 and prior and
8.0.12 and prior. Easily exploitable 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. CVSS 3.0 Base Score
4.9 (Availability impacts). CVSS Vector:
