The Oracle Linux operating system must be configured so that all Group Identifiers (GIDs) referenced in the /etc/passwd file are defined in the /etc/group file.
Severity | Group ID | Group Title | Version | Rule ID | Date | STIG Version |
|---|---|---|---|---|---|---|
| low | V-221722 | SRG-OS-000104-GPOS-00051 | OL07-00-020300 | SV-221722r958482_rule | 2025-02-20 | 3 |
| Description |
|---|
| If a user is assigned the GID of a group not existing on the system, and a group with the GID is subsequently created, the user may have unintended rights to any files associated with the group. |
| ℹ️ Check |
|---|
| Verify all GIDs referenced in the "/etc/passwd" file are defined in the "/etc/group" file. Check that all referenced GIDs exist with the following command: # pwck -r If GIDs referenced in then "/etc/passwd" file are returned as not defined in the "/etc/group" file, this is a finding. |
| ✔️ Fix |
|---|
| Configure the system to define all GIDs found in the "/etc/passwd" file by modifying the "/etc/group" file to add any non-existent group referenced in the "/etc/passwd" file, or change the GIDs referenced in the "/etc/passwd" file to a group that exists in "/etc/group". |
