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)
