Invoking server panic during CheckHostKey/Authenticate in golang.org/x/crypto/ssh

v0.1.0 - v0.51.0

Summary

Invoking server panic during CheckHostKey/Authenticate in golang.org/x/crypto/ssh

Details

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
