Figure 1 is an example of a JOP attack. In this example, the attacker's aim is to execute a system call "int 0x80" to open a new command line window. To do this, an attacker needs to modify the contents of the eax register to "0x0000000b" and the ebx register to the string "/bin/sh" before "int 0x80" is called, and the ecx and edx registers must point to the value "0x00000000". Suppose the value "0x0000000" and the string "/bin/sh" can be found in memory when the program is running. An attacker needs to construct the value "0x0000000b" himself. However, for the value "0x0000000b", when an attacker saves data to the stack through a buffer overflow, the "0x00" byte will trigger the system to terminate the read operation. This example specifically describes how the attacker uses the existing code snippet in the program to modify the value of val pushed into the stack by the attacker step by step from "0xffffff0b" to the value required by the system call "0x0000000b", thus implementing JOP attack. The following are the detailed steps of the process.

Unexpectedly, she said firmly, "We must get married."

"Let 's put it this way, Hit the wasp with ordinary bullets, One shot at most, But it's not the same with drag armour-piercing bombs, As long as it hits the big wasp, The big wasp can burn into a fireball in an instant. Then as long as you touch the same kind around you slightly, You can set them on fire, Let them burn themselves between themselves, Ordinary bullets cannot achieve this effect without this function, In fact, just like the principle of "74 spray", Although the area covered by the burning cannot be compared with the flame tongue emitted by the '74 spray', However, the effective range of traced armour-piercing firebombs is far away. They can be hit at a distance of several hundred meters, which is much stronger than the '74' spray, which takes 30 meters to fire. If you think about it, we can kill them efficiently only when hundreds of big wasps fly to a distance of 30 meters from you. The pressure is not generally large, but quite large.
