| Description | ||||
| If OL 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 OL 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. | ||||

Verify that OL 9 system-wide shared library files are group-owned by "root" with the following command:
$ sudo find -L /lib /lib64 /usr/lib /usr/lib64 ! -group root -exec ls -l {} \;
If any system-wide shared library file is returned and is not group-owned by a required system account, this is a finding.
Fix Text (F-75746r1092078_fix)
Configure the system-wide 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 group-owned by "root".
$ sudo chgrp root [FILE]
