Title
Audio devices must be owned by root. (Cat II impact)
Discussion
Globally accessible audio and video devices have proven to be another security hazard. There is software capable of activating system microphones and video devices connected to user workstations and/or X terminals. Once the microphone has been activated, it is possible to eavesdrop on otherwise private conversations without the victim being aware of it. This action effectively changes the user's microphone into a bugging device.
