·       KDM can be tricked into performing a password-less login even for

        autologin to be configured and "shutdown with password" enabled.

        This vulnerability was discovered and reported by Kees Huijgen.

·       root without properly supplying login credentials.

        vulnerabilities. Contact your OS vendor / binary package provider
