Synopsis :

An application installed on the remote host is affected by multiple
vulnerabilities.

Description :

The Microsoft Office application installed on the remote Windows host
is missing a security update. It is, therefore, affected by multiple
vulnerabilities :

- An information disclosure vulnerability exists in the
the Click-to-Run (C2R) components due to improper
handling of objects in memory. An authenticated, remote
attacker can exploit this, via a specially crafted
application, to obtain sensitive information and thereby
bypass the Address Space Layout Randomization (ASLR)
security feature. (CVE-2016-0137)

- An information disclosure vulnerability exists due to
Visual Basic macros improperly exporting a user's private
key from the certificate store while saving a document.
An unauthenticated, remote attacker can exploit this,
by convincing a user to provide the saved document, to
gain access to the user's private key. (CVE-2016-0141)

- Multiple remote code execution vulnerabilities exist in
Microsoft Office software due to improper handling of
objects in memory. A remote attacker can exploit these,
by convincing a user to open a specially crafted Office
file, to execute arbitrary code in the context of the
current user. (CVE-2016-3357, CVE-2016-3358,
CVE-2016-3359, CVE-2016-3360, CVE-2016-3361,
CVE-2016-3362, CVE-2016-3363, CVE-2016-3364,
CVE-2016-3365, CVE-2016-3381)

- A spoofing vulnerability exists in Microsoft Outlook due
to a failure to conform to RFC2046 and properly identify
the end of a MIME attachment. An unauthenticated, remote
attacker can exploit this, by convincing a user to open
a specially crafted email attachment, to cause antivirus
or antispam security features to fail. (CVE-2016-3366)
