[原文]Rakkarsoft RakNet network library 2.33 and earlier, when released before 30 May 2005, and as used in multiple products including nFusion Elite Warriors: Vietnam, allows remote attackers to cause a denial of service (infinite loop) via a zero-byte UDP packet.
Raknet contains a flaw that may allow a remote denial of service. The issue is triggered when an empty UDP datagram is received by the server, and will result in loss of availability for the service.
Upgrade to version 2.33 (05/30/2005) or higher, as it has been reported to fix this vulnerability. Note that this flaw was fixed in the 5/30/2005 release without a change in version number. An upgrade is required as there are no known workarounds.
