SV-27381r1_rule The at.deny file must not be empty if it exists.

Vulnerability discussion

On some systems, if there is no at.allow file and there is an empty at.deny file, then the system assumes everyone has permission to use the at facility. This could create an insecure setting in the case of malicious users or system intruders.

Check content

# more /var/adm/cron/at.deny If the at.deny file exists and is empty, this is a finding.

Fix text

Add appropriate users to the at.deny file, or remove the empty at.deny file if an at.allow file exists.

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.
