SV-65051r2_rule Remote file systems must be mounted with the nodev option.

Vulnerability discussion

Legitimate device files should only exist in the /dev directory. NFS mounts should not present device files to users.

Check content

To verify the "nodev" option is configured for all NFS mounts, run the following command: $ mount | grep nfs All NFS mounts should show the "nodev" setting in parentheses, along with other mount options. If the setting does not show, this is a finding.

Fix text

Add the "nodev" option to the fourth column of "/etc/fstab" for the line which controls mounting of any NFS mounts.

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.
