Oracle reports :

This Critical Patch Update contains 31 new security fixes for Oracle MySQL. 6 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4195-1 advisory.

    Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to     fix these issues.

    MySQL has been updated to 8.0.18 in Ubuntu 19.10. Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 19.04     have been updated to MySQL 5.7.28.

    In addition to security fixes, the updated packages contain bug fixes, new features, and possibly     incompatible changes.

    Please see the following for more information:
    https://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-28.html     https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-18.html https://www.oracle.com/security-     alerts/cpuoct2019.html

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

An update of the mysql package has been released.

The version of Oracle MySQL Connectors installed on the remote host is 8.0.x prior to 8.0.18 or 5.3.x prior to 5.3.14.
It is, therefore, affected by the following vulnerabilities as noted in the October 2019 Critical Patch Update advisory:

  - An unspecified, remote security vulnerability in the Connector/ODBC component of Oracle MySQL Connectors.
    (CVE-2019-2920)

  - A vulnerability in the OpenSSL subcomponent of the Connector/ODBC component of Oracle MySQL Connectors caused by the     ability to set variable nonce lengths in the ChaCha20-Poly1305 AEAD cipher. This could allow an unauthenticated,     remote attacker to affect data confidentiality and integrity. (CVE-2019-1543)

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