there were reasons why they couldn't annouce the config file workaround
when 3.3 release was made.
- saying "disabling challenge authenticaiton will make you safe"
will make the location of the bug apparent, letting script kiddies
create attack code in less than a day
(and in fact, did you see posting on bugtraq? in fact attack
code appeared in less than a day)
- ditto for "disabling protocol version 2"
i suggested markus to include the reasoning behind the way 3.3 -> 3.4
upgrade path was annouced. i think it will help a lot of people to
understand why it had to be handled this way.
