InsomniaX 2.1.8 Arbitrary Kernel Extension Loading

It was found that the loader application bundled with InsomniaX can be used to load arbitrary Kernel Extensions (kext). The loader is normally used to load a kext file that is needed to disable the Lid Sleep. A flaw has been found in the loader that allows a local attacker to load (or unload) any arbitrary kext file. Version 2.1.8 is affected.
