stunnel < 5.00 PRNG State Security Weakness

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.

Synopsis :

The remote Windows host contains a program that is affected by a
security weakness.

Description :

The version of stunnel installed on the remote host is prior to
version 5.00. It is, therefore, affected by a security weakness due to
the PRNG state not being reset for new connections where the server
forks. A remote attacker can exploit this issue to disclose sensitive
information, such as the private key used for EC (ECDSA) or DSA

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.
