This is a blog recording what I learned when doing buffer-overflow attack. strcpy(buff, 'This String Will Overflow the Buffer') As you can see that the strcpy() function will write the complete string in the array ‘buff’ but as the size of ‘buff’ is less than the size of string so the data will get written past the right boundary of array ‘buff’.Then you could use python exploits to target the vulnerability for example.Now as we all know, strcpy is vulnerable to buffer overflow. 2176,argv ) length of 517 bytes, but the buffer in bof() is only 24 bytes long. Buffer overflow is triggered by user input.
Strcpy buffer overflow exploit Because strcpy() does not check boundaries, buffer overflow will occur.
