Synopsis :

The remote Windows host is affected by multiple vulnerabilities.

Description :

The remote Windows host has a version of Microsoft Office, Office
Compatibility Pack, Office Web Apps, Microsoft SharePoint, Microsoft
Word, or Word Viewer installed that is affected by multiple
vulnerabilities :

- Multiple remote code execution vulnerabilities exist in
Microsoft Office software due to improper handling of
objects in memory. An attacker can exploit these, by
convincing a user to open a specially crafted file, to
execute arbitrary code in the context of the current
user. (CVE-2016-0021, CVE-2016-0134)

- A security feature bypass vulnerability exists in
Microsoft Office software due to an improperly signed
binary file. An attacker with write access to the target
host can exploit this, by overwriting the file with a
malicious binary with a similar configuration, to execute
arbitrary code. (CVE-2016-0057).
