Exploiting Buffer Overflow (50 points)

The attached C code (sort.c) contains a stack buffer overflow vulnerability. Please write exploit (by

modifying data.txt) to open a shell on Linux. The high level idea is to overwrite the return address with

the address of function system(), and pass the parameter "/bin/sh" to this function. Once the return

instruction is executed, this function will be called to open a shell.
