mysql-8.0 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS


MySQL could allow unintended access to network services.

Software Description:
- mysql-8.0: MySQL database


Tom Reynolds discovered that due to a packaging error, the MySQL X Plugin
was listening to all network interfaces by default, contrary to

This update changes the default MySQL configuration to bind the MySQL X
Plugin to localhost only. This change may impact environments where the
MySQL X Plugin needs to be accessible from the network. The
mysqlx-bind-address setting in the /etc/mysql/mysql.conf.d/mysqld.cnf file
can be modified to allow network access.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
  mysql-server-8.0                8.0.22-0ubuntu0.20.04.3

In general, a standard system update will make all the necessary changes.
