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.
