Description:
Luigi Auriemma reported a buffer overflow in the 'Terminator 3: War of the Machines' game. A remote server can cause a connected client to execute arbitrary code.
It is reported that a remote server can supply a specially crafted reply to a connected client to trigger an overflow in the statically sized ServerInfoTemp variable. As a result, the game can be crashed. It may also be possible to execute arbitrary code.
A demonstration exploit is available at:

===============
1) Introduction
===============
"Terminator 3: War of the Machines" is a multiplayer FPS game developed
by Clevers (http://www.clevers.com) and based on the homonym Swarzy's
movie.

2) Bug
======
The bug is a broadcast buffer-overflow affecting clients.
Everytime a user enters in the multiplayer menu, the game contacts the
master server and then each online server automatically.
The bug happens during the usage of some vulnerable instructions that
are exactly the following:
char ServerInfoTemp[200];
...
for (int i = 0; i < strlen(ServerInfo); i++) {
ServerInfoTemp[i] = toupper(ServerInfo[i]);
}
They get a string (ServerInfo) previously generated with the server's
IP and port and all the values in its reply, after which they put this
string into a new smaller buffer (ServerInfoTemp) converting the chars
to upper case.
The effects of this bug are the usual 2 known problems:
- automatic buffer-overflow (here with the upper-case limitation)
- network Denial of service, nobody can use the game online
For who wanna see the problem at runtime, the vulnerable instructions
in the executable of the pre-release demo are the loop between 004953d4
and 004953fe.
