SSH: Message Too Short
This protocol anomaly is a short SSH v1 message while performing the key exchange. This can be a misbehaving client or an attempt to tunnel through the SSH port.
Extended Description
Such a condition could indicate an SSH configuration or implementation error. It also could indicate a tunneling attempt over an SSH port, or that an attack against an SSH server or client is underway.
