CVE-2020-14145

El lado del cliente en OpenSSH versiones 5.7 hasta 8.4, presenta una Discrepancia Observable que conlleva a una filtración de información en la negociación del algoritmo. Esto permite a atacantes de tipo man-in-the-middle apuntar a unos intentos iniciales de conexión (donde ninguna clave de host para el servidor ha sido almacenada en caché por parte del cliente) NOTA: algunos informes afirman que las versiones 8.5 y 8.6 también están afectadas.
