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.旅美十年的女作家舒文突然接到其母欧阳琼教授的电话急召回国，在抵达机场意外遇见十八年前的恋人——刘思雨旅英回国，刘亦接到舒母紧急电话，命两人到达当日即赴舒宅与舒母会面。但究竟为何事，两个均不知就里。正心存疑惑，而又旧情在心头隐隐浮现时，舒文的丈夫——周玉轩不期而至，利用舒文思女之情将她带走，舒文见久别女儿晓倩，当日自己竟无法脱身，在自己家中逗留一夜。不料凌晨噩耗传来，舒母当夜心脏病猝发身亡...黄夫人不由得重新审视这丫头，见她眼神灵动，浅笑嫣然，虽面带稚气，却言语不漏半点消息，心下不知是喜是忧。CBS宣布续订《联邦调查局FBI》衍生剧《联邦调查局：通缉要犯FBI:MostWanted》第三季。CCTV financial reporters clicked on the speed measuring software of a 5G mobile phone and a 4G mobile phone at the same time and found that the download speeds of the two mobile phones were very different.本剧以1915年《青年杂志》问世到1921年《新青年》成为中国共产党机关刊物为贯穿，展现了从新文化运动到中国共产党建立这段波澜壮阔的历史画卷，讲述觉醒年代的百态人生。该剧以李大钊、陈独秀、胡适从相识、相知到分手，走上不同人生道路的传奇故事为基本叙事线，以毛泽东、陈延年、陈乔年、邓中夏、赵世炎等革命青年追求真理的坎坷经历为辅助线，艺术地再现了一批名冠中华的文化大师和一群理想飞扬的热血青年演绎出的一段充满激情、燃烧理想的澎湃岁月。戴安娜是亚马逊一族的公主，生活在天堂岛上。天堂岛是一个纯女人的国度，居民们都长生不老、头脑聪明，且拥有着巨大神力。因为一起意外事件，戴安娜离开家乡，来到了钢筋水泥的城市里，从此作为天堂岛的使者保护人类……
