Synopsis

The remote database server is affected by multiple vulnerabilities.

Description

The version of MySQL running on the remote host is 5.6.x prior to 5.6.50. It is, therefore, affected by multiple vulnerabilities, including the following, as noted in the October 2020 Critical Patch Update advisory:
