You will need to apply both patches.  The first patch 
(openbsd-sshd-kbdint-leak) affects more than PAM, it affects all other 
challenge-response authentications too so it needs wider testing.

Alternatively, for 3.9p1 set "ChallengeResponseAuthentication no" and 
"PasswordAuthentication yes" in sshd_config (and restart sshd, obviously).

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
