CVE-2018-12247

CVE-2018-12247 affects mruby 1.4.1. The issue is a NULL pointer dereference in mrb_class caused by certain .clone usage, where mrb_obj_clone in kernel.c copies flags other than MRB_FLAG_IS_FROZEN (e.g., the embedded flag). This can lead to crashes when the affected path is triggered. Connected so...
