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.芳蒂妮·阿和蒂安([快乐结局])将加盟新片[爱慕](Adoration，暂译)。法布里斯·度·沃尔斯([国王口信])执导。该片讲述12岁的保罗爱上了女孩格洛丽亚(芳蒂妮饰)。格洛丽亚是保罗母亲工作的精神病院里一个精神分裂少女。在格洛丽亚犯罪之后，保罗决定帮她逃脱，两人展开了一场疯狂的旅程。本季将揭开全新篇章，如今是改变和挑战、希望和恐惧、知识和无知并存的时代。罗西南特的船员们接到任务：探索星环之门外的新世界而《天河魔剑录》却是出乎意料的精彩，这本小说几乎吸收了《白发魔女传》所有的优点，开篇就是一段经典的复仇，故事跌宕起伏，剧情不断反转，几乎让人喘不过气来，最后以还在襁褓中的主角跌落河中而结束。有一天,被囚禁在黑暗世界的由厨菜,偶然目睹征木家的圣诞节,发现天地就是树雷王子,心中计划了一个阴谋.汉尼拔在佛罗伦萨逍遥度日；Bedelia假扮汉尼拔妻子并逐渐黑化；威尔伤了汉尼拔的心；反派"牙仙"红龙终于登场。家境优越的姜文静（孙怡 饰），因为儿时梦想，在父母的反对下偷偷考取了检察官职位，紧张的工作环境，让从小受到“花瓶式”教育的她，显得格格不入。职场上的犯错，生活上的不接地气，让这位大小姐一度陷入低谷，质疑梦想的真谛。直到律师任天宇（张昊唯 饰）如欢喜冤家一般出现在她的生活里，无数次的机缘巧合和案件的交集中，让二人渐生感情， 在一次次的案件和事件中渐渐成长。姜文静越发成长为一名合格的检察官，而任天宇身上的秘密也渐渐浮现。
