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.NBC剧集《我们这一天》宣布一次性续订2、3季，这部Dan Fogelman打造的大热剧是这个秋季档收视人数第二的广播网剧情剧。新续订的两季还是每季18集。秋原的前任石寨正当大案既破之际，被秋原爱人江城反贪局长童怀以贪污受贿罪拘捕后查无音信，江城市委书记，秋原的老同学郝尚亲自出面劝说秋原不要再查非法集资案，以免重蹈石寨覆辙，秋原出于党的纪委干部的责任和民心所怨所患，和纪委一班人马顶着来自四面八方的各种压力，甚至于冒着生命危险坚决二进兴江公司复查，终于水落石出真相大白，为江城市集资百姓排扰解难，终于把为官不廉，又狡猾奸诈，自以为打擦边球得手的政客郝尚及新贵族钟野送上了审判台并把他们的幕后支持者上告京。尉缭轻轻一笑：看来，大王是想要彻底留下卢绾啊。命所有人做好准备，枕戈待旦防备越军。夜幕降临，小镇寂静祥和。不知从哪个角落，传来了倒计时的声音。少女璐娜跪坐在黑漆漆的房间内，头上戴着一个宇航员头盔，眼睛紧盯着电视屏幕中火箭发射直播。她对航空航天格外着迷，身为修鞋匠的父亲投其所好，连女儿的生日都专门特制了一双航天靴。父女俩志趣相投，共同朝着航天梦而努力。璐娜一天天长大，她的航天梦从未消失。她努力学习，刻苦训练，小有成就，却也遭受了更多的挫折。尽管是男女同校，但由于男女比例的关系，8位主人公被集合到了所有男生的班级，通称“野郎组”，这是一部为了寻求和女生的接触而团结一致奋斗的校园喜剧剧。
