By sending a specially crafted series of packets to the LGSERVER.EXE
process that listens on TCP port 2200, it is possible to cause the process
to terminate.

Technical Details
During the authentication negotiation, the third client packet at HEX
address (DWORD) 0x11 - 0x14 in the third client packet specifies a data
length. Setting this this value to 0xff 0xff 0xff 0xff causes a read
access violation to occur, terminating the process.
