Synopsis :

A game server is running on the remote host.

Description :

host a gaming server.

Since it uses UDP as its transport layer and sends multiple UDP packets
in response to one request, an attacker can abuse it to flood a
third-party host with traffic by sending a spoofed UDP packet with the
IP address of their target as the source field.
