晚了。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.高级督察赵快乐（刘德华）在一次围剿劫匪行动中，被子弹打中头部，需休养九个月。赵复出之日，有四个积犯，在监房发难，胁持电脑专家死火德（张国强）及杀死惩教署人员越狱，警方高层震动，令赵快乐与资深警员臭口金（万梓良）合作缉捕四匪。军人的训练就是为了克服这种本能，但浙兵，已经太久没练了，似乎见到倭人就逃命已经成为了光荣传统。校花黄梓晨在惩恶整蛊直播节目中揭露一家地沟油火锅店，却被同校的李默森无意中搅局，遂认定李默森参与黑店生意、助纣为虐。许悦是一位受过良好传统教育的80后，事隔十年他与小时候一起长大，后移民美国的邻家妹妹米恩再次相遇，米恩租下了许悦隔壁的房子，两个人再度开始了邻居生活。米恩从小就喜欢许悦，且为了许悦而回国，许悦却只将米恩当妹妹看待，米恩选择默默地陪在许悦身边。许悦在经历感情欺骗、事业失利、亲戚朋友疏远之后，一度对自己从小受父亲教育影响的做人处世方式产生了怀疑，对当今社会上的诸多不良现象由不满变为妥协，开始变得自私自利。米恩了解许悦所经历的一切，不懈开导和帮助许悦，让许悦重新找回做人的方向。在两人相处过程中，许悦逐渐意识到自己对米恩的情感已经开始发生变化，他们在忙碌的工作之余、在生活的点滴小事中不断积累情感，最终修成正果。5.
