NVD Description

Note: Versions mentioned in the description apply only to the upstream rancher-machine-fips package and not the rancher-machine-fips package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
