SV-38354r1_rule Audio devices must not have extended ACLs.

Vulnerability discussion

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

Check content

Check the permissions of audio devices. Determine audio devices and class identifiers, i.e., audio should be listed as audio. # ioscan Determine audio/video device special files. # ioscan -fn -C Determine the device file mode. # ls -lL If the permissions include a "+" the file has an extended ACL, this is a finding.

Fix text

Remove the optional ACL from the file. # chacl -z [device file]

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.
