OS X host is missing a security update. It is, therefore, affected by
multiple vulnerabilities :

  - Multiple remote code execution vulnerabilities exist
    in Microsoft Office software due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit these, by convincing a user to open a
    specially crafted document file, to execute arbitrary
    code in the context of the current user. (CVE-2017-0020,
    CVE-2017-0030, CVE-2017-0031)

  - An information disclosure vulnerability exists in
    Microsoft Office due to improper disclosure of memory
    contents. An unauthenticated, remote attacker can
    exploit this to disclose sensitive system memory
    information by convincing a user to open a specially
    crafted document file. (CVE-2017-0027)

  - A denial of service vulnerability exists in Microsoft
    Office that allows an unauthenticated, remote attacker
    to cause Office to stop responding by convincing a user
    to open a specially crafted document file.
    (CVE-2017-0029)

  - An out-of-bounds read error exists in Microsoft Office
    due to an uninitialized variable. A local attacker can
    exploit this to disclose memory contents by opening a
    specially crafted document file. (CVE-2017-0105)

  - A flaw exists in Microsoft Lync for Mac due to improper
    validation of X.509 certificates. A man-in-the-middle
    attacker can exploit this, by spoofing a TLS/SSL server
    via a certificate that appears valid, to disclose or
    manipulate transmitted data. (CVE-2017-0129)");
