| Description |
|---|
| Crafted packets not conforming to Institute of Electrical and Electronics Engineers (IEEE) standards can be used by malicious people to exploit a host's protocol stack to create a Denial of Service (DoS) or force a device reset, bypass security gateway filtering, or compromise a vulnerable device. It is imperative these packets are recognized and discarded at the network perimeter. |
