# Date: 07/02/2012
# Discovered and exploited by: Fluidsignal Group -> Research Team Division
# Author: Andres Gomez and David Mora (a.k.a Mighty-D) ... Pwn and beans!
# Software Link: http://torcs.sourceforge.net/
# Version: torcs 1.3.2
# Vendor notified: 03/02/2012
# Tested on: Windows XP Service Pack 3 Spanish
# CVE : */
/*
Create template.xml file (see and the end of submission). Place both .c and template.xml files
in the same folder. Run the exploit, this will append a 'sound' section in the template file.
Move the xml file into torcs/cars/sc-f1/ and replace sc-f1.xml (F1 car Config.) for example.
Choose car and run a race. Torcs will then crash.
