OpenSSL 1.0.1 < 1.0.1c TLS/DTLS CBC Denial of Service

This script is Copyright (C) 2012-2017 Tenable Network Security, Inc.

Synopsis :

The remote host may be affected by a denial of service vulnerability.

Description :

According to its banner, the remote web server is running a version
of OpenSSL 1.0.1 earlier than 1.0.1c. As such, the OpenSSL library
itself is reportedly affected by a denial of service vulnerability.

An integer underflow error exists in the file 'ssl/d1_enc.c' in the
function 'dtls1_enc'. When in CBC mode, TLS/DTLS record length values and
explicit initialization vector length values related to TLS/DTLS
packets are not handled properly, which can lead to memory corruption and
application crashes.
