- You are running a version of OpenSSH which is older than 3.4
-
- There is a flaw in this version that can be exploited remotely to
- give an attacker a shell on this host.
-
- Note that several distribution patched this hole without changing
- the version number of OpenSSH. Since Nessus solely relied on the
- banner of the remote SSH server to perform this check, this might
- be a false positive.
-
- If you are running a RedHat host, make sure that the command :
- rpm -q openssh-server
-
- Returns :
- openssh-server-3.1p1-6
-
-
- Solution : Upgrade to OpenSSH 3.4 or contact your vendor for a patch
- Risk factor : High";
