Vulnerability discussion

File system ACLs can provide access to files beyond what is allowed by the mode numbers of the files.

Check content

Determine the audio device files for the system. Procedure: # /usr/sbin/lsdev -C | grep -i audio #aclget /dev/*aud0 Check if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL from the audio device file(s) and disable extended permissions. #acledit /

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.
