This code implements the following steps:

Connection Setup: The setup_connection function establishes a TCP connection to the target SSH server.

Handshake and Heap Preparation: The perform_ssh_handshake and prepare_heap functions handle the SSH handshake and heap preparation, respectively.

Timing Measurement: The time_final_packet function measures the time taken by the server to parse a specific packet, which is used to time the final exploit attempt.

Final Exploit Attempt: The attempt_race_condition function constructs the final exploit packet, which includes the shellcode, and sends it to the server. It attempts to time the packet send to trigger the race condition vulnerability.

The main function coordinates the overall exploitation process, including multiple attempts with different glibc base addresses.

Note that this is a simplified example, and in a real-world scenario, the exploit would need to be more robust and handle various edge cases and error conditions. Additionally, the specific details of the vulnerability, such as the memory corruption and the shellcode, would need to be tailored to the target system and the vulnerability being exploited.

Not sure why you hid the code so i tried filling it out. lol, cheers
