Fix Recommendation

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]

Check Contents

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 "%n %U" '{}' \;

If any systemwide shared library directory is not owned by root, this is a finding.
