The remote host is running a version of macOS / Mac OS X that is 11.0.x prior to 11.0.1. It is, therefore, affected by multiple vulnerabilities, including the following:

  • An out-of-bounds write issue that can lead to unexpected application termination or arbitrary code execution when opening a maliciously crafted PDF file. (CVE-2020-9876)

  • An out-of-bounds write caused by insufficient input validation that can lead to arbitrary code execution when processing a maliciously crafted image. (CVE-2020-9883)

  • A remote attacker may be able to unexpectedly alter the Mail application date due to insufficient checks.
    (CVE-2020-9941)

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