For the convenience of the experiment, we directly use the functions in libc.so.6 as the attack functions to be executed. This is a C program runtime in Linux, which holds a large number of available functions and contains system ("/bin/sh"). Therefore, we can use ROPgadget tool to obtain the code fragments that we can exploit, and use pwntool to exploit the vulnerabilities of vulnerable programs, thus achieving our attack purpose, that is, running system ("/bin/sh"). In order to facilitate the subsequent use of ROPgadget tool to find gadget and attack, it is necessary to copy the libc.so.6 file to the operation directory. First, use the "ldd" command to view the source directory, and then use the "cp" command to copy it to the operation directory.寂静之夜，保罗·欧·凯利和女友安娜驱车行驶在荒无人烟的国道上。他们要去洛杉矶参加一个朋友的婚礼，因安娜不愿乘飞机，于是只能日夜兼程赶路。夜深人静，身心俱疲，保罗和安娜在路旁找到一家汽车旅馆，决定暂时再次留宿。这间汽车旅馆分外冷清，服务生弗兰克羞涩拘谨，仿佛是一个有着诸多难以启齿故事的人。　保罗在此遇到一名神秘的男人，自此他大学时代那令他不堪回首的过去渐渐浮出水面。另一方面，弗兰克的妻子桑迪也时常逡巡在保罗和安娜房间的附近，他们仿佛堕入了一个神秘而黑色的圈套之中.幸亏海战有一个好处，打不过可以跑，除非我的帆比你小。只是越国地处东南，与大部分的诸侯相隔甚远，无法联合道一起，起不了多大作用。　　浩宇历尽周折让“雨宁”明白真相爱上了自己，不料却发现她不过是个替身。深陷痛苦的浩宇将计就计，利用红玉反击宫家，红玉夹在两个男人复杂的爱与恨之间受尽磨难。最终少华幡然醒悟以命赎罪，红玉与浩宇的爱情起死回生。经历过战地迷情
