- You are running a version of OpenSSH which is older than 3.7.1
-
- Versions older than 3.7.1 are vulnerable to a flaw in the buffer management
- functions which might allow an attacker to execute arbitrary commands on this
- host.
-
- An exploit for this issue is rumored to exist.
-
-
- 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-3.1p1-13 (RedHat 7.x)
- openssh-server-3.4p1-7 (RedHat 8.0)
- openssh-server-3.5p1-11 (RedHat 9)
-
- Solution : Upgrade to OpenSSH 3.7.1
