After that, there were several repeated exchanges of fire. Anyway, there are more or less injuries, Especially the purple venom, It's terrible. You have to peel off a layer of skin when you touch it. Fortunately, with Wang Yuanhe's experience, everything that is splashed is covered with floating soil. However, there is no good way to be bitten by that kind of monster like a dog. You can only do it hard. These two strange things have left some marks on my body, which is regarded as a "souvenir" for me to take part in the war. " When Zhao Mingkai said this, First he collapsed to hold the trouser leg of his left calf, When you pull it under your knee, put it on one side of your leg. Motioned me to look, Only then did I find out that there was a defect the size of an adult fist in his calf. The skin on it is wrinkled, Don't think, according to what he said before, This must have been caused by a dog-like "living biological weapon" bite, And after showing the bruises on his legs, He showed me the tiger's mouth on his right hand again. There is also a large scar on it, According to what he said, he was splashed with the purple venom in the last battle before the artillery group resumed firing. At that time, the epidermis quickly dissolved and rotted, so that the thumb ligament inside could be seen. However, the rescue was timely and the hand was saved. However, the scar with such a large area and a large depth could never be removed. In his words, this is also a special "memorial".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.自从父母去世后，Pangrum失去了她所有的财产。她的叔叔和阿姨抚养她长大，但当他们无力继续抚养她时，他们把她送去和英俊富有的Yai住一起，让Yai当她的监护人。Yai给了她叔叔阿姨一大笔钱，承诺他会照顾好Pangrum。于是人们开始讨论，使Pangrum看起来像Yai金色牢笼里的一只金丝雀。这让Yai的姑姑Ganda很不高兴，她害怕Pangrum会夺走他们所有的财产，于是她计划让撮合Sajee和她的侄子。但Yai喜欢的是Pangrum，但问题是，他是Pangrum的监护人，Pangrum的年纪和他妹妹Ying一般大，这看上去有悖常理。还有一个问题，他那以自我为中心的弟弟Lek也一直喜欢Pangrum。 自从父母去世，Yai接管了家族企业，并让他的左膀右臂Thanope来帮他管理公司。这让Lek很不高兴，他认为Yai不信任他这个弟弟。乾隆末年，诸皇子争位，其中最有可能继位的是为乾隆所称许的十一皇子永瑆和十五皇子永琰。为此，众大臣在朝野内外明争暗斗，二位皇子的母亲也频出奇招以讨乾隆欢心。永琰天性豁达，对此了无兴趣；永瑆却充满野心，并得和珅鼎力相助，渐占优势。为对付永琰，和珅将其心上人花椒下狱；永琰冒死救出，和珅随即派兵追杀。乾隆得知，要求和珅誓死保护。是杀是保，和珅两难，最后只好应承以先求自保；可永瑆不惜牺牲盟友，着兵全力追杀。事已至此，和珅只好携永琰逃亡。永琰之母认为永琰如此景况是因花椒，便逼花椒嫁给了永琰的好友福康安。永琰得知，误为乾隆所为，就发誓不回宫，并力荐永瑆为太子。永琰对福康安娶花椒之事一直耿耿于怀；为报复，便将其身世公诸于世，福康安无法接受一病不起。当永琰知道真相后追悔莫及，哀求乾隆骗福康安乃高贵血统；福康安终于在谎言中平静死去。此时，永瑆还惦记着皇位，永琰还想与花椒再续前缘，可惜世事难料……
