30 November 2020

MySQL could allow unintended access to network services.

Details

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

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

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