The remote host is running Mac OS X 10.12.6 or Mac OS X 10.13.6 and is missing a security update. It is, therefore, affected by multiple vulnerabilities :

  • An application may be able to read restricted memory (CVE-2019-8603, CVE-2019-8560)

  • An application may be able to execute arbitrary code with system privileges (CVE-2019-8635, CVE-2019-8616, CVE-2019-8629, CVE-2018-4456, CVE-2019-8604, CVE-2019-8574, CVE-2019-8569)

  • An application may be able to execute arbitrary code with kernel privileges (CVE-2019-8590)

  • Processing a maliciously crafted audio file may lead to arbitrary code execution (CVE-2019-8592)

  • Processing a maliciously crafted movie file may lead to arbitrary code execution (CVE-2019-8585)

  • A malicious application may bypass Gatekeeper checks (CVE-2019-8589)

  • A malicious application may be able to read restricted memory (CVE-2019-8560, CVE-2019-8598)

  • A user may be unexpectedly logged in to another users account (CVE-2019-8634)

  • A local user may be able to load unsigned kernel extensions (CVE-2019-8606)

  • A malicious application may be able to execute arbitrary code with system privileges (CVE-2019-8605)

  • A local user may be able to cause unexpected system termination or read kernel memory (CVE-2019-8576)

  • An application may be able to cause unexpected system termination or write kernel memory (CVE-2019-8591)

  • An application may be able to gain elevated privileges (CVE-2019-8577)

  • A maliciously crafted SQL query may lead to arbitrary code execution (CVE-2019-8600)

  • A malicious application may be able to elevate privileges (CVE-2019-8602)

  • A local user may be able to modify protected parts of the file system (CVE-2019-8568)

  • Processing maliciously crafted web content may lead to arbitrary code execution (CVE-2019-6237, CVE-2019-8571, CVE-2019-8583, CVE-2019-8584, CVE-2019-8586, CVE-2019-8587, CVE-2019-8594, CVE-2019-8595, CVE-2019-8596, CVE-2019-8597, CVE-2019-8601,CVE-2019-8608, CVE-2019-8609, CVE-2019-8610, CVE-2019-8611, CVE-2019-8615, CVE-2019-8619, CVE-2019-8622, CVE-2019-8623, CVE-2019-8628)

  • Processing maliciously crafted web content may result in the disclosure of process memory (CVE-2019-8607)

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