return value weakness in the Next-Generation Multicast VPN (NG-mVPN) which can result in a denial of service (DoS)
condition. An unauthenticated, remote attacker can exploit this issue, by repeatedly sending crafted, malformed IPv4
packets to a victim device, including when these packets are forwarded directly through a device, provided that the
malformed packet is not first de-encapsulated from an encapsulated format by a receiving device. This allows an
attacker to cause the system to stop responding.
