Уязвимость реализации протокола SSH средства криптографической защиты PuTTY, позволяющая нарушителю получить несанкционированный доступ к защищаемой информации
PuTTY through 0.75 proceeds with establishing an SSH session even if it has never sent a substantive authentication response. This makes it easier for an attacker-controlled SSH server to present a later spoofed authentication prompt (that the attacker can use to capture credential data, and use that data for purposes that are undesired by the client user).
