However, exploitation of this stack overflow is complicated by a few factors: Prior to overflowing the stack, the buffer with the user’s input is converted to lowercase. As a result, the exploit cannot use any gadgets which contain bytes with capital letters (ASCII 0x41-0x5A). The copy which overflows the stack is a string copy. Browser Exploitation.
