Vulnerability discussion

Without privileged group owners, audio devices will be vulnerable to being used as eaves-dropping devices by malicious users or intruders to possibly listen to conversations containing sensitive information.

Check content

Check the group owner of audio devices. Procedure: # /usr/sbin/lsdev -C | grep -i audio # ls -lL /dev/*aud0 If the group owner of an audio device is not root, sys, bin, or system, this is a finding.

Fix text

Change the group owner of the audio device. Procedure: # chgrp system

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.
