Example:? ? ?你听过一个有关警察、歌手、神经病和黑手党公主的故事吗？《猛禽小队和哈莉·奎茵》是一个只有哈莉·奎茵本人才能讲出来的超乎寻常的奇妙传奇。哥谭市最为凶残自大的恶棍罗曼·赛恩尼斯和他狂热的手下萨斯为了寻找一个年轻女孩卡斯，将这座城市翻了个底朝天。哈莉、女猎手、黑金丝雀和蕾妮·蒙托亚不期而遇，看似违和的四人组不得不团结一致、携手作战，才有可能打败罗曼。潘是个勤奋的人。自从他父母去世后，他辍学开始工作来养活自己和他的小弟弟。潘先生在他租来的房子前开了一个露天货摊，但几乎入不敷出。那是在他的一个顾客招募他为他朋友拥有的一家酒店当厨师之前。酒店老板通(音)是一位年轻而头脑发热的商人。他们实际上以前见过面，他们对彼此的印象不好。当潘发现通是这家旅馆的老板时，他立即拒绝在那里工作。然而，通要求他做这项工作，他不想被人看不起，所以决定接受这个职位。通一尝就喜欢上了潘的菜，但又不想丢脸，就跟潘说菜难吃。这两个人见面总是打架。但是过了一段时间，他们每天的争吵发展成了一些特别的事情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.吴凌珑却说什么也不愿放下正常的儿子，多少年来她都暗暗抽泣，跟菩萨许愿，跟佛祖许愿，跟太上老君也许愿，让她儿子获得健康，如今也不知道是哪位神仙灵验了，回头挨个都得上柱香。
