Description
If AlmaLinux OS 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 AlmaLinux OS 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 are owned by "root" with the following command: $ find -L /lib /lib64 /usr/lib /usr/lib64 ! -user root -exec ls -l {} \; If any systemwide shared library file is not owned by root, this is a finding.

✔️ Fix
Configure the systemwide shared library files (/lib, /lib64, /usr/lib and /usr/lib64) to be protected from unauthorized access. Run the following command, replacing "[FILE]" with any library file not owned by "root". $ chown root [FILE]
