This script is Copyright (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

Arbitrary code can be executed on the remote host through Microsoft
Office.

Description :

The version of Microsoft Office installed on the remote host has
multiple vulnerabilities :

- The path used for loading external libraries is not
securely restricted. An attacker could exploit this by
tricking a user into opening an Office file in a
directory that contains a malicious DLL, resulting in
arbitrary code execution. (CVE-2011-0107)

- An unspecified code execution vulnerability exists in
Office. A remote attacker could exploit this by
tricking a user into opening a maliciously crafted
Office file. (CVE-2011-0977)
