|
|
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.
