We'll see... given that sshd is just one of many possible argv[0] it may have choosen to act on, I'm going to be a little paranoid until it's been fully analyzed. It just takes half an hour to reinstall, I have some shows to catch up on anyway :)
But it's unclear if earlier versions are also vulnerable.
And if it did nasty things to your machine, how do you make sure that the backups you have do not include ways for the backdoor to reinstate itself?
I don't backup the whole system, just a specific list of things in /home.
