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.1937年，日军的铁骑在中华大地上肆虐。中共地下党员夏家河带着电台前往沦陷区大连，赴交通站接头时，意外碰见当年的初恋女友王大花，王的丈夫唐全礼误以为两人旧情复燃，打乱了夏的计划，两人同时被捕入狱，入狱前夏将电台托付于王大花。王大花倾其家产欲救出两人，但丈夫却蒙冤而死，得救的只有夏家河。对夏抱有成见的王大花稀里糊涂将电台带至大连，引出重重危机，几经辗转终于成功交付共产党。王大花为谋生，在大连开起饭店，与夏家河所开的诊所共处一街，两人逐渐从冤家到相依相帮，历经磨难，屡次完成革命任务，立下奇功。在夏家河的引导下，王大花终于从一名普通的家庭妇女成长为一个坚定的共产主义战士。6.2 Reduce SYN-RECEIVED time-Liu Shiying (Financial Writer and Founder of President's Reading Club)玉米则被他们含沙射影的话气得发昏，想要辩解，哪能插得进去。Name: Wang Zha
