As I said, I was not closely following the story, but IIRC the SSH Protocol version 1 has a principal design flaw that *can* *not* *be* *fixed* without breaking the protocol. There were, of course, additional issues with implementations, but ssh1 never really was secure, and never will be. I'm not making any statement about the practical relevance of the attack here, nor do I know of any successful break in using this weakness, so YMMV. cheers -- vbi -- this email is protected by a digital signature: http://fortytwo.ch/gpg NOTE: keyserver bugs! get my key here: https://fortytwo.ch/gpg/92082481
