Nice challenge and thank you @w3th4nds. Your challenges always are not too easy but not too difficult. I’m not an new to heap exploitation but enjoyed this. I solved this challenge by an unintended way (but not cheating) since the flag told me the intended way. So, There are at least two ways to the flag.

If you want a hint, PM me.
