CVE-2003-0390

This exploit targets a buffer overflow vulnerability in the Libopt library (opt-3.18 and prior) by overflowing the opt_atoi() function with a crafted argument. It uses a stack-based buffer overflow to overwrite EIP and execute arbitrary shellcode, providing a reverse shell.

This code is a stub demonstrating the vulnerable use of Libopt's opt_atoi() function, which is prone to a buffer overflow. It lacks exploit payloads or mechanisms to trigger arbitrary code execution.
