Vulnerability discussion

Cron daemon control files restrict the scheduling of automated tasks and must be protected. Unauthorized modification of the cron.deny file could result in Denial of Service to authorized cron users or could provide unauthorized users with the ability to run cron jobs.

Check content

Determine the cron.deny file's group owner. # ls -lL /var/adm/cron/cron.deny If the file is not group-owned by root, bin sys or other, this is a finding.

Fix text

Change the group-owner of the cron.deny file. # chgrp root /var/adm/cron/cron.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.
