The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5022-3 advisory.
USN-5022-1 fixed several vulnerabilities in MySQL. This update provides the corresponding update for Ubuntu 16.04 ESM.
Original advisory details:
Multiple security issues were discovered in MySQL and this update includes
new upstream MySQL versions to fix these issues.
MySQL has been updated to MySQL 5.7.35 on Ubuntu 16.04 ESM.
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-5-7-35.html
https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-26.html
https://www.oracle.com/security-alerts/cpujul2021.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.
