The remote host is running a version of macOS / Mac OS X that is 10.15.x prior to 10.15.7 Security Update 2021-002 Catalina It is, therefore, affected by multiple vulnerabilities, including the following:

  • An application may be able to execute arbitrary code with system privileges due to insufficient permission checks (CVE-2020-3838).

  • A memory corruption vulnerability could allow an application read access to restricted memory (CVE-2021-1808).

  • A memory corruption vulnerability could allow an application to cause unexpected system termination or to write kernel memory (CVE-2021-1828).

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