Oracle reports :

This Critical Patch Update contains 49 new security patches for Oracle MySQL. 10 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials. The highest CVSS v3.1 Base Score of vulnerabilities affecting Oracle MySQL is 9.8.

MariaDB is affected by CVE-2021-2166 and CVE-2021-2154 only

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Parser). Supported versions     that are affected are 5.7.29 and prior and 8.0.19 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-2021-2144)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3755 advisory.

    MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld)     and many client programs and libraries.

    The following packages have been upgraded to a later upstream version: mysql (8.0.21).
