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.刘子樱车祸昏迷不醒，令她惊奇的是自己的灵魂脱离了身体，子樱偶然认识了不得志的漫画家杨易，她通过一部手机一直鼓励杨易，帮助杨易实现了梦想。他们之间虽然从未见面，却早已成为了彼此最珍贵的人，最后子樱病危，脱险后不认识杨易了，而杨易又通过自己的方式让刘子樱找回了那段过去。　　年轻的乾隆由于经验不足，往往事与愿违，越想展示自己的才华，越是常常陷入尴尬。而李卫一心想辞官归里，可越想躲越躲不过，还因为他的老辣和老道，将一件件棘手的难事办得滴水不漏，每次帮乾隆保住了面子，于是别人想爬爬不上去的，李卫却想下还死活下不来……　　转眼间剑已长大成人，当上警察，正直的剑因不愿贪污而只能负责看守证物房。剑在证物房翻出英的辫子，二人终相认。当年驾祸给英的叶家声（张兆辉）升做探长，把关公像重新移位，英冤魂得以重获自由。英挂念华，剑积极助她寻找华的下落；而剑亦得英的帮助而屡破奇案，许是宿命使然，英找到了华，却发现华如她一样被屈做替死鬼……If you can play doubles, you will be prompted on the interface.Regionally, North and East China are the regions with the largest application of industrial software, accounting for about half of the country's total.
