SV-86677r3_rule The Red Hat Enterprise Linux operating system must be configured so that the cron.allow file, if it exists, is owned by root.

Vulnerability discussion

If the owner of the "cron.allow" file is not set to root, the possibility exists for an unauthorized user to view or to edit sensitive information.

Check content

Verify that the "cron.allow" file is owned by root. Check the owner of the "cron.allow" file with the following command: # ls -al /etc/cron.allow -rw------- 1 root root 6 Mar 5 2011 /etc/cron.allow If the "cron.allow" file exists and has an owner other than root, this is a finding.

Fix text

Set the owner on the "/etc/cron.allow" file to root with the following command: # chown root /etc/cron.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.
