MS KB3062760: Update for Vulnerability in Juniper Networks Windows In-Box Junos Pulse Client (FREAK)

This script is Copyright (C) 2015-2017 Tenable Network Security, Inc.


Synopsis :

The remote Windows host has VPN client software installed that is
affected by multiple vulnerabilities.

Description :

The remote Windows host is missing KB3062760, which resolves multiple
OpenSSL vulnerabilities in the Juniper Networks Windows In-Box Junos
Pulse client shipped with Windows 8.1 :

- A flaw exists with ECDH handshakes when using an ECDSA
certificate without a ServerKeyExchange message. This
allows a remote attacker to trigger a loss of forward
secrecy from the ciphersuite. (CVE-2014-3572)

- A security feature bypass vulnerability, known as FREAK
(Factoring attack on RSA-EXPORT Keys), exists due to the
support of weak EXPORT_RSA cipher suites with keys less
than or equal to 512 bits. A man-in-the-middle attacker
may be able to downgrade the SSL/TLS connection to use
EXPORT_RSA cipher suites which can be factored in a
short amount of time, allowing the attacker to intercept
and decrypt the traffic. (CVE-2015-0204)

- A flaw exists when accepting DH certificates for client
authentication without the CertificateVerify message.
This allows a remote attacker to authenticate to the
service without a private key. (CVE-2015-0205)
