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.一次古怪的事故将住在郊区的少年保罗传送到了一个平行世界！这个世界中从未发生过工业革命，强有力的名为“Spellbinder、迷惑者”（也可以翻译成“咒缚”）的团体利用公众的恐惧和无知统 治世界。依靠少女瑞亚娜的帮助，保罗必须同时从两个世界寻求帮助，否则就会被永远流放在这个世界中。Starz续订《权欲》第六季，该季首播集将由Curtis “50 Cent” Jackson负责执导。这部惊人的纪录片回顾无药可医的英国爱滋危机大流行早期，当时HIV检测呈现阳性几乎等于宣判死刑。许多受访人士从未对媒体公开谈论过那些痛苦难忘的早期日子，而这可能是他们唯一一次的访谈。本片穿插了演员-强纳森布雷克的访谈，他与病毒共同生活已经超过30年。视频中讲述世人绝不能淡忘的一段绝望时期。《爱滋过后》是对人类同情心、力量、爱心与韧性的非凡见证，并确保那些声音永远不会被遗忘早已心意相通，金刚伏魔圈修炼到化境。　　小分队内部的猜忌越来越严重，众人身上仿佛都有疑点，洪风锁定了莫三甲为叛徒，莫三甲却拿出证据证明洪风才是叛徒，小分队一度濒临绝裂……
