Apple has released iOS 12.1.4 software update to fix FaceTime privacy bug that could have allowed an Apple user to call you via the FaceTime video chat service and hear or see you before you even pick up the call. The bug (CVE-2019-6223) was discovered by 14-year-old Grant Thompson of Catalina Foothills High School while he was trying to set up a Group FaceTime session with his friends. Apple has confirmed to “compensate” the family and help towards the teenager’s future education costs as part of its Bug Bounty program.
