NVD Description

Note: Versions mentioned in the description apply only to the upstream mruby package and not the mruby package as distributed by Debian.

An issue was discovered in mruby 1.4.1. There is a NULL pointer dereference in mrb_class, related to certain .clone usage, because mrb_obj_clone in kernel.c copies flags other than the MRB_FLAG_IS_FROZEN flag (e.g., the embedded flag).
