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)

  - An out-of-bounds read error exists in Bluetooth due to improper input sanitization. An attacker can     exploit this to read restricted memory. (CVE-2019-8853)

  - An arbitrary code execution vulnerability exists in Mail due to improper input validation. An     unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary     JavaScript code. (CVE-2020-3884)

  - An arbitrary file read vulnerability exists in Time Machine due to improper state management. An     unauthenticated, local attacker can exploit this to read arbitrary files and disclose sensitive     information. (CVE-2020-3889)

  - An arbitrary code execution vulnerability exists in AppleGraphicsControl, Bluetooth, IOHIDFamily, and the     kernel due to memory initialization and corruption issues. An attacker can exploit this to bypass     authentication and execute arbitrary commands with kernel privileges. (CVE-2020-3892, CVE-2020-3893,     CVE-2020-3904, CVE-2020-3905, CVE-2020-3919, CVE-2020-9785)

  - An arbitrary code execution vulnerability exists in Apple HSSPI Support due to a memory corruption issue.
    An attacker can exploit this to bypass authentication and execute arbitrary commands with system     privileges. (CVE-2020-3903)

  - A logic issue exists in TCC due to an unspecified reason. An attacker can exploit this, via a maliciously     crafted application, to cause bypass code signing. (CVE-2020-3906)

  - An out-of-bounds read error exists in Bluetooth due to improper input validation. An unauthenticated local     attacker can exploit this to cause a denial of service or read kernel memory. (CVE-2020-3907,     CVE-2020-3908, CVE-2020-3912)

  - A buffer overflow condition exists in libxml2 due to improper bounds checking and size validation. An     attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.
    (CVE-2020-3909, CVE-2020-3910, CVE-2020-3911)

  - A privilege escalation vulnerability exists in due to improper permission validation. An unauthenticated,     remote attacker can exploit this, to gain elevated access to the system. (CVE-2020-3913)

  - An information disclosure vulnerability exists in the kernel due to improper memory handling. An attacker     can exploit this to read restricted memory. (CVE-2020-3914)
