Vulnerability 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.

Check content

Check the owner of audio devices. Determine audio devices and class identifiers, i.e., audio should be listed as audio. # ioscan Determine audio device special files. # ioscan -fn -C

Fix text

Change the owner of the audio device. # chown root

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
