"The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.5 Big Sur. It is, therefore,
affected by multiple vulnerabilities including the following:

  - An application may be able to execute arbitrary code with kernel privileges (CVE-2021-30805)

  - Opening a maliciously crafted file may lead to unexpected application termination or arbitrary code execution
    (CVE-2021-30790)

  - A local attacker may be able to cause unexpected application termination or arbitrary code execution
    (CVE-2021-30781)

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