Eavesdropping FaceTime possible by bug

With FaceTime, the video calling service on Apple devices, it is possible to listen to other users.

The leak was discovered this week by Apple customers and appears on all devices from iPhone to iMac. It occurs when a user starts a group conversation via FaceTime. Not only sound but also image can be leaked. The callers will see the picture when those who call them happen to press an on / off or volume button.
