Fix Recommendation

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 with a mode more permissive than "755".

$ sudo chmod 755 [DIRECTORY]

Check Contents

Verify the systemwide shared library directories have mode "755" or less permissive with the following command:

$ sudo find -L /lib /lib64 /usr/lib /usr/lib64 -perm /022 -type d -exec ls -l {} \;

If any systemwide shared library directory is found to be group-writable or world-writable, this is a finding.
