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 :

- 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-2016-7230, CVE-2016-7231,
CVE-2016-7232, CVE-2016-7234, CVE-2016-7235,
CVE-2016-7236, CVE-2016-7245)

- 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)

- A denial of service vulnerability exists due to improper
handling of objects in memory. An unauthenticated,
remote attacker can exploit this by convincing a user to
open a specially crafted file, resulting in a crash of
the application. (CVE-2016-7244)
