SV-26436r1_rule The /etc/group file must not have an extended ACL.

Vulnerability discussion

The /etc/group file is critical to system security and must be protected from unauthorized modification. The group file contains a list of system groups and associated information.

Check content

Verify /etc/group has no extended ACL. # ls -l /etc/group If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix text

Remove the extended ACL from the file. # chmod A- /etc/group

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.
