Description
If SLEM 5 were to allow 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 SLEM 5 with software libraries that are accessible and configurable, as in the case of interpreted languages. Software libraries also include privileged programs which execute with escalated privileges. Only qualified and authorized individuals must be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications.

Check Text ( C-65025r996363_chk )
Verify the system-wide 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 ! -group root -type f -exec stat -c "%n %G" '{}' \; If any system wide library file is returned, this is a finding.

Fix Text (F-64933r996364_fix)
Configure the library files to be protected from unauthorized access. Run the following command: > sudo transactional-update shell > sudo find /lib /lib64 /usr/lib /usr/lib64 ! -group root -type f -exec chgrp root '{}' \; > exit > sudo reboot
