nNetObject.cpp in Armagetron Advanced 2.8.2 and earlier allows remote attackers to cause a denial of service (application crash) via a large owner value, which causes an assert error.
Armagetron 0.2.6.0 and earlier and Armagetron Advanced 0.2.7.0 and earlier allow remote attackers to cause a denial of service (network disconnection) via an empty UDP packet, which is not properly distinguished from the "no new packets" state of the associated socket.
