Vulnerability discussion

If shell files are owned by users other than root or bin, they could be modified by intruders or malicious users to perform unauthorized actions.

Check content

Check the ownership of the system shells. # cat /etc/shells | xargs -n1 ls -lL If any shell is not owned by root or bin, this is a finding.

Fix text

Change the ownership of the shell with incorrect ownership. # chown root

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.
