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: [email protected] [email protected] [email protected] [email protected] -Jay Libove, CISSP
