=========== Description =========== 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.
