刘邦抬头看着泪流满面的吕雉。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.秦淼见他真的兜到了鱼，欢喜极了，就要上前来收拾。烦和怕，终究是有区别的，比如人们烦蚊子，却不怕蚊子，人们怕蛇。/Friends of New into the pit Look Here/Abstract public int calculation (int num1, int num2);由十几个农民工组成的小建筑公司总经理张小五，在她30岁生日到来的时候收到了一连串的打击：未婚夫另觅新欢舍她而去，公司周转不灵发不出工人工资，房东嫌她拖欠房租将她赶了出去，合作方结束项目欠款远走他乡，家里亲戚为了讨钱也对她穷追不舍……面对这一件件无奈的生日“礼物”，遭遇了事业、情感双重打击的张小五做的第一件事是取光自己存折上所有的钱，先给手下的农民工发放工资，之后暂住在天桥下的大卡车里，一边尽力追讨欠款、寻找项目挽救濒临破产的装修公司，一边躲避着家人的纠缠……无独有偶，从美国远渡重洋回到北京的温雅彬这几天也不大顺利。作为国际知名建筑集团的年轻接班人，他不喜欢继承家业，不喜欢商人的身份，更不喜欢家里安排的婚姻大事。他带着拍摄中国电影的梦想回到北京，却做着所有他不喜欢的事。两个不顺心的人在一次意外后邂逅，小五得知雅彬就是她要追债的公司新负责人后，对温开始穷追不舍，而雅彬也发现小五就是他苦苦挖掘的电影原型，于是对她一路跟踪……最终执着的小五收获了自己的一份爱情和事业。
