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.
