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.The fluorescent lamp mode shooting is closest to the human eye feeling on the scene.一辈子要对着一个丑、脾气坏、无涵养的女生……唉，吴明不禁为这个自行车青年默哀一声。该剧由Zach Galifianakis主演，并且由Galifianakis 、Louis C.K. 和Jonathan Krisel (Portlandia的导演）共同创作。主要描述Galifianakis扮演的Chip Baskets，渴望成为一名受人敬仰的小丑。在 巴黎一家没人报名的著名小丑学校被踢出校后（噗，没人报名还著名个噗啊），Chip唯一找到的工作，却是在加州当一名牛仔。 该剧第一季为10集，计划在2016年首播。不战而屈人之兵，方是上策，然对李敬文这样的人，一切手段和心思都是多余的，只要真心待他就够了。
