I need a C script expert to help me fix a buffer overflow in a C script for a Capture The Flag (CTF) challenge. The overflow needs to allow exploitation via "ret2libc". I've been unable to exploit it due to some stack misplacement issues. Requirements: - Must be highly skilled in C programming. - Proven experience with buffer overflow and "ret2libc" exploitation. - Familiarity with Linux platform. - Ability to provide a comprehensive write-up upon project completion. The project will only be marked as completed after you issue the write-up and we verify it's working. It is a relatively simple task and it should only take an hour or two if you know what you are doing. I'm currently facing a segmentation fault. Please let me know if you can help.

As an experienced programmer with more than 4 years of experience, I offer my expertise in C programming to solve your CTF challenge. I understand the importance of securing buffer overflow and am also familiar with the intricacies of "ret2libc" exploitation. Moreover, I have worked extensively on the Linux platform, adding to my prowess in C development. What sets me apart is my ability to provide not just a solution but also a comprehensive write-up. I will document the steps taken to fix the buffer overflow and how ret2libc exploitation was accomplished along with troubleshooting that may come handy for future reference. Given the relative simplicity of the task at hand, I am confident that I will be able to address your issue within a matter of hours, provided you can give me remote access to your system for troubleshooting. Let's collaborate and bring a secure and efficient solution to this CTF challenge while ensuring complete documentation to end this project on a high note. Looking forward to hearing from you soon!
