The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6 Security Update 2020-002, 10.14.x prior to 10.14.6 Security Update 2020-002, or 10.15.x prior to 10.15.4. It is, therefore, affected by multiple vulnerabilities :

  - Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor     Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.
    (CVE-2019-14615)

  - ** DISPUTED ** In Sudo through 1.8.29, an attacker with access to a Runas ALL sudoer account can     impersonate a nonexistent user by invoking sudo with a numeric uid that is not associated with any user.
    NOTE: The software maintainer believes that this is not a vulnerability because running a command via sudo     as a user not present in the local password database is an intentional feature. Because this behavior     surprised some users, sudo 1.8.30 introduced an option to enable/disable this behavior with the default     being disabled. However, this does not change the fact that sudo was behaving as intended, and as     documented, in earlier versions. (CVE-2019-19232)
