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.如此一来蛮人的势力将会有很大程度的发展。NTP magnification attack实在是她太快了，拳头又狠。首先，他一反常态，兵行险招，出乎叔父意料之外。岁月荏苒，杜拉拉早已不是那只升职路上匍匐前进的职场菜鸟 她坐镇SH人事经理已驾轻就熟，不日就要问鼎总监级别；和王伟的甜蜜恋情瓜熟蒂落，领证结婚过上了幸福的二人世界。
