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.Picture above first.我们年纪大了，可撑不住，也要家去睡了。她找个机会出来玩好容易么？过了这回，还不知能不能有下回哩。同时派出军队寻找营救汉王刘邦，至于大梁如今已经没有丝毫的意义。街机爱好者周齐天在发誓戒掉游戏后，突然收到来自一位穿着性感的旗袍女人赠送的“狂人乐园”游戏卡，没想到就是这张看似普通的游戏卡让周齐天还有他的朋友踏上了匪夷所思的救母之路。周齐天等人穿越到游戏中闯关，经历的不仅有真人大战怪物的爽快感，更多的还是随时面临生与死的抉择，尤其面对狡诈多变的大boss，周齐天一度命悬一线。
