他转身吩咐魏铁：你不必上去了。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.青年血染衣衫，神情疲惫，但是依然紧紧握着手里的刀，眼神刚毅似铁。　　随着肾上腺素被柴米油盐取代，罗易明和俞越发现爱情的升级版——婚姻并不是他们想象的样子，他们每一天都会遇到新问题，都会遭遇新的考验。在日常琐事中，他们摸索着婚姻之道，解决着他们的一个又一个“第一次”。蓝星是一位偶像歌手，与男友慕克维感情相相当好，一次节目的意外，让蓝星变成植物人，而克维则是对她百般悉心的照顾，蓝星与克维的经纪人兼好友Gina则不断地鼓励与支持着克维。中山翔是一位华裔日本人，在日本广告公司工作，因台湾分公司有状况，被派到台湾支援。他住进公司安排的房子，没想到这间屋子原本是蓝星的住处，而蓝星的魂魄也不时的出现在这…On the other hand, if this View does not consume the down event, then the onTouchEvent () of the parent View will call back layer by layer to pass the down event to the parent View, so the consumption of the event is also a process of passing the event.节奏 - EXO
