Sorry, that was stupid of me. First build the new sshd and start it on
a high port. If you're supposed to have enough access to update sshd,
you should have access enough to run something on a high port.

True. Much worse than logging in over telnet would be to run a
temporary sshd on a high port.  Wait...

I did not suggest running it there for a long time but rather just
enough time to allow you to update your system. You're presuming that
your attacker is presuming that you're smart and not using clear-text
protocols to administer your server.

True. That's why you're the admin and why you're updating sshd. You have root.
