"The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6. It is, therefore, affected by
multiple vulnerabilities :

  - An application may be able to read restricted memory
    (CVE-2019-8691, CVE-2019-8692, CVE-2019-8693)

  - Extracting a zip file containing a symbolic link to an
    endpoint in an NFS mount that is attacker controlled may
    bypass Gatekeeper (CVE-2019-8656)

  - A remote attacker may be able to cause arbitrary code
    execution (CVE-2019-8648, CVE-2018-19860, CVE-2019-8661)

  - A remote attacker may be able to leak memory
    (CVE-2019-8646, CVE-2019-8663)

  - A remote attacker may be able to cause unexpected
    application termination or arbitrary code execution
    (CVE-2019-8641, CVE-2019-8660)

  - An application may be able to execute arbitrary code
    with system privileges (CVE-2019-8695, CVE-2019-8697)

  - An issue existed in Samba that may allow attackers to
    perform unauthorized actions by intercepting
    communications between services (CVE-2018-16860)

  - An application may be able to execute arbitrary code
    with kernel privileges (CVE-2019-8694)

  - A remote attacker may be able to view sensitive
    information (CVE-2019-13118)

  - An attacker may be able to trigger a use-after-free in
    an application deserializing an untrusted NSDictionary
    (CVE-2019-8662)

  - Visiting a malicious website may lead to address bar
    spoofing (CVE-2019-8670)

  - The encryption status of a Time Machine backup may be
    incorrect (CVE-2019-8667)

  - Parsing a maliciously crafted office document may lead
    to an unexpected application termination or arbitrary
    code execution (CVE-2019-8657)

  - Processing maliciously crafted web content may lead to
    universal cross site scripting (CVE-2019-8690,
    CVE-2019-8649, CVE-2019-8658)

  - Processing maliciously crafted web content may lead to
    arbitrary code execution (CVE-2019-8644, CVE-2019-8666,
    CVE-2019-8669, CVE-2019-8671, CVE-2019-8672,
