Mac OS X : Cisco AnyConnect Secure Mobility Client 2.x / 3.x < 3.1(5170) Multiple OpenSSL Vulnerabilities

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


Synopsis :

The remote host is affected by multiple vulnerabilities.

Description :

The remote host has a version of Cisco AnyConnect prior to 3.1(5170).
It is, therefore, potentially affected by the following
vulnerabilities :

- An error exists related to the implementation of the
Elliptic Curve Digital Signature Algorithm (ECDSA) that
could allow nonce disclosure via the 'FLUSH+RELOAD'
cache side-channel attack. (CVE-2014-0076)

- A buffer overflow error exists related to invalid DTLS
fragment handling that could lead to execution of
arbitrary code. Note this issue only affects OpenSSL
when used as a DTLS client or server. (CVE-2014-0195)

- An error exists related to DTLS handshake handling that
could lead to denial of service attacks. Note this
issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An unspecified error exists that could allow an
attacker to cause usage of weak keying material
leading to simplified man-in-the-middle attacks.
(CVE-2014-0224)
