OpenSSH < 2.9.9p1 Resource Limit Bypass

This script is Copyright (C) 2011-2012 Tenable Network Security, Inc.

Synopsis :

The remote SSH service is affected by a denial of service

Description :

According to its banner, the remote host is running a version of
OpenSSH earlier than 2.9.9p1. Such versions fail to initiate a
Pluggable Authentication Module (PAM) session if commands are executed
with no pty. A remote, unauthenticated attacker, exploiting this
flaw, could bypass resource limits (rlimits) set in pam.d.
