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.　　被父亲抛弃的殷丽英与母亲过着艰辛的日子，母亲生下的弟弟也在饥寒交迫中夭折，母亲哭瞎了双眼，这些惨剧让幼年的丽英深深埋下了仇恨的种子，从此开始计划复仇，她刻苦学习，拼命打工，并选择了编剧专业作为大学主修专业，她深知一毕业，她的复仇计划便会开始实行。故事开始于一座孤岛之上，在这里，居住着一群动物们，其中，十分勇敢对于新鲜事物有着无尽好奇心的鹦鹉麦克（大卫·霍华德·桑顿 David Howard Thornton 配音）对小岛外面的世界十分的向往，可是其他的动物们却并不这么想，小岛是他们的安乐窝，小岛以外对于他们来说就是致命的危险地带。沛公与张良匆匆回府，不明就里的樊哙迎上了，笑嘻嘻说道：恭喜沛公即将荣任关中王。Zhang Liang took six classes, each lasting 15 minutes, and was said to have prepared for three or four months.
