Vulnerability discussion

Reserved GIDs are typically used by system software packages. If non-system groups have GIDs in this range, they may conflict with system software, possibly leading to the group having permissions to modify system files.

Check content

# more /etc/passwd Confirm all accounts with a GID of 99 and below are used by a system account. If a GID reserved for system accounts (0 - 99) is used by a non-system account, this is a finding.

Fix text

Change the primary group GID numbers for non-system accounts with reserved primary group GIDs (those less or equal to 99). # usermod -g

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.
