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

  • Arbitrary code execution when processing a maliciously crafted image. (CVE-2021-30835, CVE-2021-30847)

  • An integer overflow issue due to insufficient input validation, which can lead to arbitrary code execution by an unauthenticated attacker when processing a maliciously crafted PDF. (CVE-2021-30860)

  • Arbitrary code execution when processing a maliciously crafted dfont file. (CVE-2021-30841, CVE-2021-30842, CVE-2021-30843)

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