     [compat.c compat.h sshconnect2.c sshd.c version.h]
     OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of connections
     using the curve25519-sha256@libssh.org KEX exchange method to fail
     when connecting with something that implements the spec properly.

     Disable this KEX method when speaking to one of the affected
     versions.
