OpenSSH SSHFP Record Verification Weakness

Medium Nessus Plugin ID 78655


A secure shell client on the remote host could be used to bypass host verification methods.


According to its banner, the version of OpenSSH running on the remote host is 6.1 through 6.6.

It is, therefore, affected by a host verification bypass vulnerability related to SSHFP and certificates that could allow a malicious SSH server to cause the supplied client to inappropriately trust the server.


Update to version 6.7 or later or apply the vendor patch.
