Fix Recommendation

Configure the library files to be protected from unauthorized access. Run the following command:

$ sudo find /lib /lib64 /usr/lib -perm /022 -type f -exec chmod 755 '{}' \;

Check Contents

Verify the system-wide shared library files contained in the directories "/lib", "/lib64", and "/usr/lib" have mode 0755 or less permissive with the following command:

$ sudo find /lib /lib64 /usr/lib -perm /022 -type f -exec stat -c "%n %a" '{}' \;
/usr/lib64/pkcs11-spy.so

If any files are found to be group-writable or world-writable, this is a finding.
