- You are running OpenSSH 3.7p1 or 3.7.1p1.

- These versions are vulnerable to a flaw in the way they handle PAM
- authentication and may allow an attacker to gain a shell on this host.
-
- *** Note that Nessus did not detect whether PAM is being enabled
- *** in the remote sshd or not, so this might be a false positive.
-
-
- Solution : Upgrade to OpenSSH 3.7.1p2 or disable PAM support in sshd_config
