"The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 11.1.1 It is, therefore,
affected by multiple vulnerabilities.

- A remote code execution vulnerability exists in WebKit due to improper memory handling.
  An unauthenticated, remote attacker can exploit this, via a specifically crafted
  web page to to execute arbitrary code or cause a denial of service
  (CVE-2018-4199, CVE-2018-4201, CVE-2018-4218, CVE-2018-4233).

- An information disclosure vulnerability exists in WebKit. An unauthenticated,
  remote attacker can exploit this, via a specifically crafted web page,
  to disclose potentially sensitive information (CVE-2018-4190).

- An out-of-bounds read error exists in WebKit due to improper input validation.
  An unauthenticated, remote attacker can exploit this, via a specifically crafted web page
  that leverages a getWasmBufferFromValue  during WebAssembly compilation to execute arbitrary
  code (CVE-2018-4222).");
