SV-27389r1_rule The at.allow file must have mode 0600 or less permissive.

Vulnerability discussion

Permissions more permissive than 0600 (read, write and execute for the owner) may allow unauthorized or malicious access to the at.allow and/or at.deny files.

Check content

Check the mode of the at.allow file. # ls -lL /var/adm/cron/at.allow If the at.allow file has a mode more permissive than 0600, this is a finding.

Fix text

Change the mode of the at.allow file. # chmod 0600 /var/adm/cron/at.allow

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.
