Fix Recommendation

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

# sudo find /lib /usr/lib /lib64 ! -user root -type f -exec chown root '{}' \;

Check Contents

Verify the system-wide shared library files contained in the directories "/lib", "/lib64" and "/usr/lib" are owned by root.

Check that the system-wide shared library files are owned by root with the following command:

# sudo find /lib /usr/lib /lib64 ! -user root -type f -exec stat -c "%n %U" '{}' \;
