The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2021-001 Mojave, 10.15.x prior to 10.15.7 Security Update 2021-001 Catalina, or 11.x prior to 11.2. It is, therefore, affected by multiple vulnerabilities, including the following:

  • A logic issue existed resulting in memory corruption. This was addressed with improved state management.
    An application may be able to execute arbitrary code with kernel privileges. (CVE-2020-27904)

  • A logic issue existed that allowed applications to execute arbitrary code with kernel privileges.
    (CVE-2021-1750)

  • An out-of-bounds-write caused by improper input validation allowed maliciously crafted USD files to unexpectedly terminate an application or cause arbitrary code execution. (CVE-2021-1762)

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