Я вспоминал. На мой взгляд это всё раздувание шума из ничего.
На мой взгляд вообще хорошо, что уязвимости обнаруживают. Значит 
программой кто-то пользуется. Было бы хуже, если бы до неё не 
было дела - точно была бы дырявая, как решето.

P.S. В Сизиф был отправлена новая версия, не имеющая уязвимости.

P.P.S.
И вообще те десятки сообщений о rssh, которые на меня обрушились, 
смахивают на DoS :)
