SV-27071r1_rule All Group Identifiers (GIDs) referenced in the /etc/passwd file must be defined in the /etc/group file.

Vulnerability discussion

If a user is assigned the GID of a group that does not exist on the system, and a group with that GID is subsequently created, the user may have unintended rights to the group.

Check content

Perform the following to ensure there are no GIDs referenced in /etc/passwd not defined in /etc/group: # usrck -n ALL If GIDs referenced in /etc/passwd are not defined in /etc/group are returned, this is a finding.

Fix text

Add a group to the system for each GID referenced without a corresponding group. # smitty mkgroup

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.
