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.孙海山是‘柳杨拳’的传人。一辈子最大愿望就是把武馆发扬光大，但他古板的教学方式根本招不到学员。而把武馆当生意做的师弟白宗元却经营的有声有色，桃李满天下。为了争到那块代表正宗的百年老匾与孙海山展开了明夺暗抢，甚至不惜利用儿子白云峰对孙铁铮的感情，结果弄巧成拙，反而促成了儿子与离婚妈妈小丽的婚事，让他后悔不迭。孙铁铮三十了还没有找到对象。妈妈彭红霞把这一切的原罪归于孙海山，为此两人吵吵闹闹几十年，一句话不合离了婚。林一浩的到来，给传统的武馆带来了生机，也被柳杨拳博大精深的奥妙拳术深深打动，中华武魂精神成就了他和孙铁铮的爱情，也让孙海山和彭红霞重新走到了一起。In response to this problem, Osaka Weaving House has developed a "small black trousers".
