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.我弟弟才十二，你们抓他，太没天理了。11岁的少年八神太一（藤田淑子 配音），和伙伴石田大和（风间勇刀 配音）、武之内空（水谷优子 配音）、泉光子郎（天神有海 配音）、太刀川美美（前田爱 配音）、城户丈（菊池正美 配音）、高石武（小西寛子 配音）一起参加了夏令营，一次意外却被神秘地送到了一个多彩的数码世界。在那里，他们得到了叫做“数码宝贝”的搭档。进入数码世界后，八神太一一行人遇到了凶恶的怪兽贝壳兽，眼看大家都要被抓住的时候，太一的亚古兽忽然进化成为暴龙兽，拯救了他们。进化到底是怎么回事情？数码世界究竟是什么？无数的谜团出现在被召选的小朋友们面前，精彩的冒险就这样开始了……Console.log ("I am the technical director responsible for the technical interview");可能会救了娘之后，却发现媳妇根本没抓住自己结的绳索，又或许媳妇已经沉水，又或许媳妇已经被水流冲走……我以为，这些都不重要，重要的是他没有丢弃老娘，但也没有因为娘而丢弃媳妇……人群一片寂静，大家虽然都是男人，却都明白了玄武将军的想法。
