Oracle reports :

This Critical Patch Update contains 48 new security patches for Oracle MySQL.

The highest CVSS v3.1 Base Score of vulnerabilities affecting Oracle MySQL is 8.

NOTE: MariaDB only contains CVE-2020-14812 CVE-2020-14765 CVE-2020-14776 and CVE-2020-14789

The version of MySQL running on the remote host is 8.0.x prior to 8.0.22. It is, therefore, affected by multiple vulnerabilities, including the following, as noted in the October 2020 Critical Patch Update advisory:

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Security: LDAP Auth).   Supported versions that are affected are 8.0.21 and prior. Easily exploitable vulnerability allows   low privileged attacker with access to the physical communication segment attached to the hardware   where the MySQL Server executes to compromise MySQL Server. Successful attacks of this vulnerability   can result in takeover of MySQL Server (CVE-2020-14878).

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions   that are affected are 8.0.21 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 takeover of MySQL Server (CVE-2020-14828)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that   are affected are 5.7.31 and prior and 8.0.21 and prior. Easily exploitable vulnerability allows low   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-2020-14775). 

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 20.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4604-1 advisory.
