Descriptions

The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service (connection-slot exhaustion) by periodically making many new TCP connections.

La configuración por defecto de OpenSSH hasta v6.1 impone un límite de tiempo fijado entre el establecimiento de una conexión TCP y el inicio de sesión, lo que hace que sea más fácil para los atacantes remotos provocar una denegación de servicio periódicamente haciendo muchas conexiones TCP nuevas.
