    descriptionThe remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.4. It is, therefore, affected by multiple vulnerabilities, including: - Mounting a maliciously crafted NFS network share may lead to arbitrary code execution with system privileges. (CVE-2019-8508) - An application may be able to execute arbitrary code with kernel privileges. (CVE-2019-8529) - A malicious application may be able to execute arbitrary code with system privileges (CVE-2019-8549)
