### Description

In Eclipse Wakaama (formerly liblwm2m) 1.0, core/er-coap-13/er-coap-13.c in lwm2mserver in the LWM2M server mishandles invalid options, leading to a memory leak. Processing of a single crafted packet leads to leaking (wasting) 24 bytes of memory. This can lead to termination of the LWM2M server after exhausting all available memory.
