SV-38364r1_rule The at directory must not have an extended ACL.

Vulnerability discussion

If the at directory has an extended ACL, unauthorized users could be allowed to view or to edit files containing sensitive information within the at directory. Unauthorized modifications could result in Denial of Service to authorized at jobs.

Check content

Check the permissions of the directory. # ls -lLd /var/spool/cron/atjobs If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix text

Remove the optional ACL from the directory. # chacl -z /var/spool/cron/atjobs

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.
