SV-26556r1_rule The at.deny file must have mode 0600 or less permissive.

Vulnerability discussion

The at daemon control files restrict access to scheduled job manipulation and must be protected. Unauthorized modification of the at.deny file could result in Denial of Service to authorized at users or provide unauthorized users with the ability to run at jobs.

Check content

Check the permissions of the file. # ls -lL /etc/cron.d/at.deny If the file has a mode more permissive than 0600, this is a finding.

Fix text

Change the mode of the file. # chmod 0600 /etc/cron.d/at.deny

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.
