Cryptographic weakness on Debian systems

I worked on the openssh side of the update for both Debian and Ubuntu (largely on Canonical
time, but dealing with openssh in Debian as well). Unfortunately I only managed to get the
openssh update into the upload queue after the Debian system administration team locked down
SSH access in various places, which it transpired also knocked out the ability to publish
further updates for a while ... with any luck this will be sorted out soon.
