| Description | ||||
| If TOSS 5 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 TOSS 5 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-282543r1201327_chk)
Verify the systemwide shared library directories are group-owned by "root" with the following command:
$ sudo find /lib /lib64 /usr/lib /usr/lib64 ! -group root -type d -exec stat -c "%n %G" '{}' \;
If any systemwide shared library directory is returned and is not group-owned by a required system account, and is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
Fix Text (F-87009r1201326_fix)
Configure the systemwide shared library directories (/lib, /lib64, /usr/lib and /usr/lib64) to be protected from unauthorized access.
Run the following command, replacing "[DIRECTORY]" with any library directory not group-owned by "root".
$ sudo chgrp root [DIRECTORY]
