NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-server package and not the openssh-server package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The verify_host_key function in sshconnect.c in the client in OpenSSH 6.6 and earlier allows remote servers to trigger the skipping of SSHFP DNS RR checking by presenting an unacceptable HostCertificate.
