VMware ESX 3 Server: GEN002340 (in version v1 r2)

Title

Audio devices must be owned by root. (Cat II impact)

Discussion

Audio and video devices that are globally accessible have proven to be another security hazard. There is software that can activate 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 to a bugging device.

Check Content

Check the owner of audio devices. If the owner of an audio device is not root, this is a finding.

Fix Text

Change the owner of the audio device. # chown root <audio device>
