"The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as
referenced in the USN-6583-1 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 5.7.44 in Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

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