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).
