In iOS before 11.4.1, watchOS before 4.3.2, tvOS before 11.4.1, Safari before 11.1.1, macOS High Sierra before 10.13.6, a spoofing issue existed in the handling of URLs. This issue was addressed with improved input validation.

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).

The version of Apple iOS running on the mobile device is prior to 11.4.1. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS that is 10.13.x prior to 10.13.6. It is, therefore, affected by multiple vulnerabilities in the following components:

 - Accounts
 - AMD
 - APFS
 - ATS
 - Bluetooth
 - CFNetwork
 - CoreCrypto
 - CUPS
 - DesktopServices
 - Intel Graphics Driver
 - IOGraphics
 - Kernel
 - libxpc
 - LinkPresentation
 - Perl
 - Ruby

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6. It is, therefore, affected by multiple vulnerabilities.

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

The remote host is running Mac OS X 10.11.6 or Mac OS X 10.12.6 and is missing a security update. It is therefore, affected by multiple vulnerabilities.

According to its banner, the version of Apple TV on the remote device is prior to 11.4.1. It is, therefore, affected by multiple vulnerabilities as described in the HT208936 security advisory.

Note that only 4th and 5th generation models are affected by these vulnerabilities.
