This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

An application installed on the remote macOS or Mac OS X host is
affected by multiple vulnerabilities.

Description :

The Microsoft Office application installed on the remote macOS or Mac
OS X host is missing a security update. It is, therefore, affected by
multiple vulnerabilities :

- Multiple remote code execution vulnerabilities exist
due to improper handling of objects in memory. An
unauthenticated, remote attacker can exploit these by
convincing a user to visit a specially crafted website
or open a specially crafted Office file, resulting in
the execution of arbitrary code in the context of the
current user. (CVE-2016-7213, CVE-2016-7228,
CVE-2016-7229, CVE-2016-7231, CVE-2016-7232,
CVE-2016-7234, CVE-2016-7235, CVE-2016-7236)

- An information disclosure vulnerability exists due to an
out-of-bounds read error caused by an uninitialized
variable. An unauthenticated, remote attacker can exploit
this by convincing a user to open a specially crafted
Office file, resulting in the disclosure of memory
contents. (CVE-2016-7233)
