Description

A heap overflow in IOHIKeyboardMapper::parseKeyMapping allows kernel memory
corruption in Mac OS X before 10.10. By abusing a bug in the IORegistry, kernel
pointers can also be leaked, allowing a full kASLR bypass.

Tested on Mavericks 10.9.5, and should work on previous versions.

The issue was patched silently in Yosemite.
