SV-64297r1_rule The at directory must be group-owned by root, bin, sys, or cron.

Vulnerability discussion

If the group of the "at" directory is not root, bin, sys, or cron, unauthorized users could be allowed to view or edit files containing sensitive information within the directory.

Check content

Check the group ownership of the file. Procedure: # ls -lL /var/spool/at If the file is not group-owned by root, bin, sys, daemon or cron, this is a finding.

Fix text

Change the group ownership of the file to root, bin, sys, daemon or cron. Procedure: # chgrp <"at" directory>

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.
