--> There is also a "Hosts" directive to restrict logins to specific
IP addresses. It definitely helps you to restrict the number of
IPs and users that can connect, but it does not really protect you
against the security vulnerability. Because if someone connects from
an allowed IP with an allowed user name, he can exploit the
vulnerability. But of course chances for this are much smaller than if
everybody can try.
