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.张杨看了几幅后，纳闷道：田少爷这字倒还罢了，黄豆的字怎会如此刚毅？都说字如其人，你小子狡猾狡猾的，这字不像你写的。倾情记录小吒吒作为一个顶天立地的金刚芭比渡过的七年人生。小吒吒，本名哪吒，曾用名李狗蛋，前世为太2真人大弟子，被师父投胎于李府，才得到了这段普通而又幸福的平民生活。...锦绣地老板之一赵鹏被绑架，其妻冯四会带着一盘赵鹏被绑架的录像带寻求警方庇护。六组成员通过调查发现，此次绑架是冯四会一手所为，幕后指使为陈雪。六组成员顺藤摸瓜，锦绣地16枪案的真正幕后黑手、指使葛雄连环杀人的徐副主任被双规。神秘女人陈雪也因八年前的一起合同诈骗案被拘审。内陆小城芸江市，一批刚毕业的年轻女孩子集到这里，在警队队长宋健明的带领下，发生了很多故事。家庭富足的宁檬，被警服所吸引，拒绝接管舅舅的公司，毅然进入大队工作。为了还亲人清白，她孤军奋战，最终成长为一名真正警察；在警察世家长大的李露西，为了工作，忍痛与男友分离，为了照顾多病的父亲，她只能把自己内心的情感委屈雪藏；而整天做梦的依典典本以为警察生活会有所不同，怀揣美好憧憬的她来到大队后，才发现工作是枯燥无味的，最终被人利用。虽然索菲仍然背负着一些关于性的老式观念，但她也很羡慕贝拉那迷人、自由的女孩对城市生活的看法。然后她会遇到很多漂亮的新朋友。从不断壮大的充满活力、性欲旺盛的女朋友和身边的男人那里，我们可以学到更多关于生活和爱情的知识。The civil aviation pilots that the main question wants to ask should refer to 121 pilots, not to the civil aviation pilots including 91 navigable and 135 business planes in general.
