 A strange hunt that has never been seen before or since.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.This.mediator = mediator;本剧以蜚声中外的我国四大名剧之一《桃花扇》为蓝本，生动再现了秦淮八艳的历史传奇及才子佳人流传久远的红尘绝恋。 候朝宗（周杰饰）、李香君（曹颖饰），人面桃花，重谱了旧欢新怨；柳如是、陈圆圆（赵靓饰），一代佳丽，再现薄命红颜；董小婉、冒辟疆，才子佳人，总是有情无缘；韩赞同、吴三桂，一代枭雄，功过任人评说；崇祯帝、弘光帝，九五之尊，顷刻灰飞烟灭；杨龙友、李辰君，江湖豪强，各有动人风采……虞子期听闻有魏国人前来，也颇为惊讶，匆匆赶到营地的辕门候选总统遭遇“牢狱之灾”，瓦夏这次又将带给我们怎样的惊喜？
