SV-60953r1_rule Duplicate Group IDs (GIDs) must not exist for multiple groups.

Vulnerability discussion

User groups must be assigned unique GIDs for accountability and to ensure appropriate access protections.

Check content

The root role is required. Check that group IDs are unique. # getent group | cut -f3 -d":" | sort -n | uniq -c |\ while read x ; do [ -z "${x}" ] && break set - $x if [ $1 -gt 1 ]; then grps=`getent group | nawk -F: '($3 == n) { print $1 }' n=$2 | xargs` echo "Duplicate GID ($2): ${grps}" fi done If output is produced, this is a finding.

Fix text

The root role is required. Work with each respective group owner to remediate this issue and ensure that the group ownership of their files are set to an appropriate value.

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.
