A validation issue was addressed with improved input sanitization. This issue is fixed in macOS Mojave 10.14.6. An application may be able to read restricted memory.

The remote host is running Mac OS X 10.12.6 or Mac OS X 10.13.6 and is missing a security update. 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-2019-8649,     CVE-2019-8658, CVE-2019-8690)

  - 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,     CVE-2019-8673, CVE-2019-8676, CVE-2019-8677,     CVE-2019-8678, CVE-2019-8679, CVE-2019-8680,     CVE-2019-8681, CVE-2019-8683, CVE-2019-8684,     CVE-2019-8685, CVE-2019-8686, CVE-2019-8687,     CVE-2019-8688, CVE-2019-8689)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

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 :
