SV-40084r1_rule All files and directories must have a valid group owner.

Vulnerability discussion

Files without a valid group owner may be unintentionally inherited if a group is assigned the same GID as the GID of the files without a valid group owner.

Check content

Determine if any file on the system does not have a valid group owner. # find / -nogroup -print If any such files are found, this is a finding.

Fix text

Change the group owner for each file without a valid group owner. # chgrp /tmp/a-file-without-a-valid-group-owner

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.
