The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to Mojave Security Update 2021-005 Mojave. It is, therefore, affected by multiple vulnerabilities including the following:

  • A double free issue could be exploited which could lead to arbitrary code execution with kernel privileges. This issue was addressed with improved memory management. (CVE-2021-30703)

  • An issue could be exploited by tricking a user into opening a maliciously crafted file may lead to unexpected application termination or arbitrary code execution. This issue was addressed by removing the vulnerable code. (CVE-2021-30790)

  • An input validation issue could be exploited which could lead to arbitrary code execution with kernel privileges. This issue was addressed with input validation. (CVE-2021-30805)

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