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.　　池秀媛饰演大女儿，作为小说家英国曼彻斯特，一栋郊区房子里的住户们各自过着不同于彼此的人生。看似有着一墙之隔，生活却将他们牵到了一起，像每个人一样，看似平常的人生中总会有着一些不同寻常。随着人物故事的逐渐交织，他们开始因为各自隐藏的秘密，以从未料想到的方式被联系到一起……故事始于上世纪八十年代初期，改革开放的春风已经率先吹绿了中国南方，个体经济如雨后春笋般遍地开放，家住瑞安古树村的周老顺召开家庭会议，宣布了一个石破天惊的决定：一是卖掉房子让13岁的女儿阿雨跟随表舅去意大利上学，二是他和媳妇赵银花带着16岁的儿子麦狗闯荡温州城，寻找商机发大财。他的决定断了自己也断了孩子的退路，一家人为此分隔天涯，踏上了不同的道路。女儿阿雨远赴他乡，孤身在异国打拼，历尽商海沉浮，尝尽人间冷暖，终于开创了自己的事业，在遥远的异国他乡赢得了尊重和地位。原来如此，原来如此。　　缉毒大队一举歼灭了以毛杰父母为首的贩毒据点。毛杰知道了安心的真实身份后，开始实行疯狂的报复，张铁军死在了毛杰的手上。"Charming Card" Creates a New Format of Cultural Travel and Opens the Era of "Tourism Plus"
