The type 0x80 forces the server to perform a cycle from zero to the 32 bit number (so max 0xffffffff) specified in that data block. The maximum size of a packet supported by the game is 1400 bytes in which is possible to place max 233 blocks of this type causing the freeze of a server for over 2 hours (tested with a fast CPU). ####################################################################### =========== 3) The Code =========== http://aluigi.org/poc/usurdat.zip ####################################################################### ====== 4) Fix ====== No fix ####################################################################### --- Luigi Auriemma http://aluigi.org _______________________________________________ Full-Disclosure - We believe in it.
