This script is Copyright (C) 2014-2017 Tenable Network Security, Inc.


Synopsis :

The remote device is missing a vendor-supplied security patch.

Description :

According to its self-reported version, the version of IVE / UAC OS
running on the remote host is affected by multiple vulnerabilities :

- An error exists in the function 'ssl3_read_bytes'
that could allow data to be injected into other
sessions or allow denial of service attacks. Note
this issue is only exploitable if
'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2010-5298)

- An error exists in the function 'do_ssl3_write' that
could allow a NULL pointer to be dereferenced leading to
denial of service attacks. Note this issue is
exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is
enabled. (CVE-2014-0198)

- 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)

- An unspecified error exists related to anonymous ECDH
ciphersuites that could allow denial of service
attacks. Note this issue only affects OpenSSL TLS
clients. (CVE-2014-3470)
