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.　　火山喷发了，这些人的命运纠结在一起。为了看见明天的太阳，他们必须与过去和解，合力为自己也为众生在绝境中寻找一条生路。 这是一个关于爱与勇气、选择与放弃、自救与他救的中国式英雄的故事。When the primary server fails, an automatic failover is forced to start without asking other Sentinels for comments, but it will send the other Sentinels an up-to-date configuration, and the other Sentinels will update according to this configuration.在“TokyoExplosion”的未知灾难背后，有一名暗中活跃的契约者——代号“黑”，被称为黑色死神的男人。制造了与“组织”敌对的事件，黑和他的同伴，身为DOLL的银一起踏上了逃亡之路。他们一边击退组织派来的刺客，一边向南方前进。在漫无尽头孤独的逃亡旅程中，两人可以信赖依靠的，只剩下彼此而已……Briefly summarize how the simulator is called.屡考不中的秀才杜云腾（陈浩民饰）阴差阳错的被误认成为欢喜县县令，与知晓杜云腾底细的捕快麦亚堂（林子聪饰）上演了一场夺权大战，并与欲卧底在衙门的女山贼曹天娇（林源饰），冒牌神医后人华盈盈，以及自卑的武功高手小强等人组成欢喜县衙。在两种价值观的碰撞之下，杜云腾与麦亚堂斗得难分难舍，从官场斗到情场，两人也在不知不觉间被对方所改变。他们联手破获案件、整顿欢喜县、惩恶扬善铲平恶霸、修建学堂造福百姓，在这过程中他们发现并最终成功地挫败了一场巨大的阴谋。Button-Unrivaled Flurry
