===============
1) Introduction
===============


Haegemonia is a strategic space combat game developed by Digital
Reality (http://www.digitalreality.hu) released in the 2002.
This game has excellent ambient musics but its network protocol seems a
bit bugged...

The bug is a classical reading of unallocated memory caused by the
sending of a packet containing a chat message with a too big 32bit
number identifying the length of the message.
