| Description |
|---|
| If RHEL 9 allowed any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. This requirement applies to RHEL 9 with software libraries that are accessible and configurable, as in the case of interpreted languages. Software libraries also include privileged programs that execute with escalated privileges. |
| ℹ️ Check |
|---|
| Verify the systemwide shared library files contained in the directories "/lib", "/lib64", "/usr/lib", and "/usr/lib64" are group owned by root with the following command: $ sudo find /lib /lib64 /usr/lib /usr/lib64 -type f -name '*.so*' ! -group root -exec stat -c "%n %G" {} + If any output is returned, this is a finding. |
| ✔️ Fix |
|---|
| Configure the systemwide shared library files contained in the directories "/lib", "/lib64", "/usr/lib", and "/usr/lib64" to be group owned by root with the following command: $ sudo find /lib /lib64 /usr/lib /usr/lib64 -type f -name '*.so*' ! -group root -exec chown :root {} + |
