Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference via the coap_client_exchange_blockwise2 function. An attacker can cause a system crash and potentially execute unauthorized commands by sending a specially crafted CoAP packet that leads to a null pointer being dereferenced during a memcpy operation.
