You can also set ChallengeResponseAuthentication to no (I would make
sure SkeyAuthentication is also no) in the mean time.
It's completely absurd that the OpenSSH people recommended blind upgrades
to a PrivSep version of OpenSSH, rather than just suggesting to people that
they disable ChallengeResponseAuthentication. I guess they're not so "Open"
