MS10-049: Vulnerabilities in SChannel could allow Remote Code Execution (980436)

This script is Copyright (C) 2010-2017 Tenable Network Security, Inc.

Synopsis :

It may be possible to execute arbitrary code on the remote Windows
host using the Secure Channel security package.

Description :

The remote Windows host is running a version of the Secure Channel
(SChannel) security package that is affected by one or more of the
following vulnerabilities :

- The SChannel authentication component allows a client to
renegotiate the connection after the initial handshake,
which could be abused to inject information into an encrypted
connection, effectively sending traffic spoofing an
authenticated client. (CVE-2009-3555)

- The way that SChannel validates a certificate request message
sent by a server could lead to a denial of service or even allow
execution of arbitrary code if an attacker can trick a user on
the affected system into connecting to malicious web server over
SSL or TLS. (CVE-2010-2566)
