Raknet Denial of Service
<http://www.rakkarsoft.com> Raknet is a multi-license (GPL, shareware and
commercial) network library for games developed by
<http://www.rakkarsoft.com> Rakkarsoft. It has been used in many open and
closed source games like those developed by <http://www.n-fusion.com>
Raknet based games vulnerable to denial of service when server receives
maliciously crafted UDP packet.
* Raknet network library versions 2.33 and prior (before 30 May 2005).
* Raknet network library version 2.33 (05/30/2005) version not changed.
An UDP packet of 0 bytes is able to freeze the game server. The problem is
that when an empty packet is received the server should close the socket
and return to the main menu (the first bug) but before doing that it
enters in an endless loop that executes Sleep(10) until the main thread is
active (but never terminates).
<http://www.rakkarsoft.com/#Downloads> Version 2.33 (05/30/2005).
The version number has not been changed so be sure to have the patched
version released the 30 May 2005 or later.
