| V-257922 | RHEL-09-232210 | SV-257922r1044988_rule | CCI-001499 | medium |
| 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. | ||||

Check Text (C-257922r1044988_chk)
Verify the systemwide shared library directories are owned by "root" with the following command:
$ sudo find /lib /lib64 /usr/lib /usr/lib64 ! -user root -type d -exec stat -c "%U %n" {} \;
If any systemwide shared library directory is not owned by "root", this is a finding.
Fix Text (F-61587r1044987_fix)
Configure the systemwide shared library directories within (/lib, /lib64, /usr/lib and /usr/lib64) to be protected from unauthorized access.
Run the following command, replacing "[DIRECTORY]" with any library directory not owned by "root".
$ sudo chown root [DIRECTORY]
