UBTU-16-010250 - The Ubuntu operating system must not be configured to allow blank or null passwords.

Information

If the operating system allows empty passwords, anyone could log on and run commands with the privileges. Empty passwords should never be used in operational environments.

Solution

Remove any instances of the 'nullok' option in files under '/etc/pam.d/' to prevent logons with empty passwords.
