The NHI card’s web service component has a heap-based buffer overflow vulnerability due to insufficient validation for packet origin parameter length. A LAN attacker with general user privilege can exploit this vulnerability to disrupt service.
Solution:
The product writes data past the end, or before the beginning, of the intended buffer.
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor.
