An issue was discovered in certain Apple products. macOS before 10.13.4 is affected. The issue involves the "kext tools" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

The remote host is running a version of macOS that is 10.13.x prior to 10.13.4. It is, therefore, affected by multiple vulnerabilities in the following components :

 - Admin Framework
 - APFS
 - ATS
 - CoreFoundation
 - CoreText
 - Disk Images
 - Disk Management
 - File System Events
 - iCloud Drive
 - Intel Graphics Driver
 - IOFireWireFamily
 - Kernel
 - kext tools
 - LaunchServices
 - Mail
 - Notes
 - NSURLSession
 - NVIDIA Graphics Drivers
 - PDFKit
 - PluginKit
 - Quick Look
 - Security
 - Storage
 - System Preferences
 - Terminal
 - WindowServer

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 affecting the following components :

  - ATS
  - CFNetwork Session
  - CoreFoundation
  - CoreTypes
  - curl
  - Disk Images
  - iCloud Drive
  - Kernel
  - kext tools
  - LaunchServices
  - PluginKit
  - Security
  - Storage
  - Terminal
