Vulnerability discussion

Globally accessible audio and video devices have proven to be security hazards. 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 mode of audio devices. # ls -lL /dev/audio If the mode of audio devices are more permissive than 0660, this is a finding.

Fix text

Change the mode of the audio device. # chmod -R 0660 /dev/audio

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.
