mkryszto/PreventSystemKeysExploit
This app demonstrates possibility to override some system keys behaviour (home, power button) without having appropriate permission. On official release ZNH0EAO2NM it allows to bypass android.permission.PREVENT_POWER_KEY permission which allows to override power button behaviour. On latest nighties where above permission is changed to android.permission.PREVENT_SYSTEM_KEYS it also allows to override behaviour of home button and possibly menu. Since that permission has signature|privileged protection level this seems like serious security vulnerability.
