buffer overflow 1- picoCTF practice challenges { Binary Exploitation }
Показать описание
This is a challenge on picogym practice ,that has a buffer overflow vulnerability. This vulnerability is as a result of using gets() function which is a risky function in that we cant specify how much we can read from the user!
Instead ,for good coding practices you can use fgets()
So we overflow the buffer with the address of win function to get us the flag :)
