  - 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,
