===============
1) Introduction
===============
Master of Orion III is a spatial strategy game developed by Quicksilver
(http://www.quicksilver.com) and released in February 2003.

=======
2) Bugs
=======
-------------------
A] allocation error
-------------------
Each data block exchanged between clients and server is preceded by a
32 bits number used to specify its size.
This amount of data is automatically allocated by the game and if it is
too big, and so unallocable, the game automatically exits.
----------------------
B] big nicknames crash
----------------------
The game uses some anti buffer-overflow protections but if an attacker
makes multiple consecutive connections (variable between 1 and 10)
using big nicknames, the game crashs.

4) Fix
======
No fix.
Developers will not fix this problem unless there are significant
incidents reported.
