Technical details
The _nx_snmp_utility_object_id_get function does not validate claimed OID data length against actual buffer size when BER multibyte length encoding is used. A remote attacker can send a crafted SNMP packet with an oversized multibyte OID length, causing an out-of-bounds read that decodes heap memory as OID values and writes them into the agent's internal OID buffer. On systems with memory protection this causes DoS via crash; on bare metal systems the corrupted state persists silently.
