  • Look for JavaScript triggering the vulnerable code path via a for-in loop combined with a for-of loop reassigning the loop variable, which exploits the BytecodeGenerator::emitGetByVal incorrect optimization in WebKit JSC.
  • ·The vulnerability is in the WebKit component and affects multiple Apple products; patched versions are iOS 11, Safari 11, iCloud 7.0 for Windows, iTunes 12.7 for Windows, and tvOS 11. On Debian, the fix is in webkit2gtk 2.18.1-1.
  • ·Exploitation requires processing maliciously crafted web content, meaning the attack surface is any WebKit-based browser or web-rendering component on affected platforms.
