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.电视剧版《唐山大地震》改编自华裔女作家张翎的中篇小说《余震》，由知名导演姚晓峰执导。这个故事讲述了一对在地震中被分开的母女，32年后意外的重逢再一次勾起了大家痛苦的回忆。小说曾经被冯小刚搬上大屏幕并感动了无数观众。剧情方面，编剧霍昕表示，”电视剧版将非常完整地呈现原著的故事情节，并将电影版中的精华部分加入进去。”万登的情感经历、美国的婚姻生活等等在电视剧中都得以延续和发展。Structural patterns, as the name implies, discuss the structure of classes and objects and are mainly used to deal with the combination of classes or objects.
