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.At the second meeting (December 27, 2016), when I attended the official election, I voluntarily applied to become a nominal SAA assistant, the de facto SAA.布成龙（张卫健饰）乃“武林鸿儒”布崇文独孙，自幼父母双亡，由爷爷一手带大，平日爱呼朋引伴，舞文弄墨，毫无忧愁。一日，武林盟主上官一剑（张复建饰）与扶桑鬼冢的比武大赛上，布崇文意外丧生，成龙伤心不已，而布家总管计昆却趁此时谋夺布家家产，成龙被赶出布府，又被杀手追杀，危急时幸遇杀猪贩子霍一刀（胡均饰）所救，两人便义结金兰，开始闯荡江湖。上官一剑女儿上官红（陈德容饰）为医父病，与管家四娘（邱淑宜饰）前往云梦山上寻找解药，不料一路危机四伏，幸有人称七决剑的萧逸龙（焦恩俊饰）出手相救，逃过一劫。成龙对上官红情有独钟，灵蛇夫人（李欣饰）的爱徒青丝（梁又南饰）和成龙邂逅于山洞中，明珠视他为托付终生的对象，纠缠不断。可爱率直的霍明珠与阴险妖娇的佘青丝，同时爱上聪颖活泼的布成龙，然而，布成龙却不领情，和冷峻风流的萧逸龙同时爱上娇生惯养的上官红，偏偏娇俏的上官红根本不理布成龙，独钟萧逸龙，但是天不从人愿，萧逸龙竟是上官红同父异母的哥哥……强民强国强种、杀敌卫国，国术已经脱离单纯的搏击战斗之术，升华成一种精神。2.4Xiao Wang took a sip of coffee.
