The full name of JOP is Jump-oriented programming, and attacks are similar to ROP attacks. It also exploits existing code snippets in binary executables for attacks. ROP uses ret instructions to change the control flow of the program, while JOP attacks use indirect jump and indirect call instructions (indirect call instructions) to change the control flow of the program. When a program executes an indirect jump or an indirect call, The program will obtain the destination addresses of its jumps from the specified registers. Because these jump destination addresses are stored in the registers and the attacker can modify the contents of the registers by modifying the contents of the stack, this allows the destination addresses of indirect jumps and indirect calls in the program to be attacked by the attacker.String exp = "8 +8";王晓安直爽女编剧|性格直爽、有点鲁莽，为人仗义，会玩会吃，练就一手好厨艺的焦虑女编剧。赫枫游戏公司副总，滑雪大神，长相帅气，风度翩翩，内心闷骚，注重形象，追求完美。林津津是一名演员，也是个重度公主病患者，喜欢被人追捧，自我为中心。叶楠某雪具店老板，喜欢 王晓安，林津津的 出现改变了风向，最终在王晓安和众多雪友的鼓励支持下，敞开心扉将林津津变为雪具店老板娘。虽说无招却是以普天下剑法之招数为根基，因而其变化之多端不逊于总决式。他们没有实际的证据证明刘邦的生死，但只需要将这个消息散播开，汉国方面的很多举动就显得疑点重重，让人由不得不信。若干年后的人类社会，一款由梦公司发行的游戏风靡全球，就在游戏狂热吸粉时，却屡屡发生玩家被困、神秘失踪等事件，PAD遂派遣“天狼”成员冷峰以游戏工程师欧阳雪的保镖身份进入游戏进行调查。两人进入游戏后，却意外发现这里其实就是异空间的封存地，而游戏，也不过是“猫头鹰”的人体实验基地。随着众多玩家被救，同时为了阻止“猫头鹰”进入异空间得到核心，打破他们继续人体实验的阴谋，双方展开了一场殊死较量。The next four patterns, including this pattern, are all the relationships between classes and do not involve inheritance. When learning, you should remember induction and the diagram at the beginning of this article. The observer mode is well understood, similar to email subscription and RSS subscription. When we browse some blogs or wikis, we often see RSS icons. This means that when you subscribe to the article, you will be notified in time if there are subsequent updates. In fact, in a nutshell, when an object changes, other objects that depend on the object will be notified and will change with it! Objects are a one-to-many relationship. Let's look at the diagram first:
