I got a packet capture of one of the SSH2 sessions trying to log in as a
couple of illegal usernames. The contents of one packet suggests an
attempt to buffer overflow the SSH server; ethereal's SSH decoding says
"overly large value".
It didn't seem to work against my system (I see no strange processes
running; all files changed in past ten days look normal).
I am cross-posting this message and the attached tcpdump packet capture
file to the following places to let better people than I analyze it:
openssh-unix-dev@xxxxxxxxxxx
secureshell@xxxxxxxxxxxxxxxxx
full-disclosure@xxxxxxxxxxxxxxxx
vulnwatch@xxxxxxxxxxxxx
