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.爱情开始的时候，我们往往都不知道是爱情，两个都曾在爱情中受过伤，不相信爱情的人，开始一步一步相识、相知、相爱，有过怀疑和波澜，也有过误会和遭遇人生的低谷，但两人在相爱的过程中，愈发感受到对方才是那个能够托付余生的那个人。A low temperature stop valve, Unlike Example 1, Comprises a valve body 1 and a valve cover 2, A valve stem 3 is arrange in that valve body 1, One end of the valve stem 3 is provided with a valve disc 4, The other end of the valve stem 3 is provided with an adjusting handwheel 5, A low portion of that disc 4 is provided with a guide sleeve 6, The guide sleeve 6 is fixed by means of a connecting piece and a spring pad 8, Between that disc 4 and the guide sleeve 6 is provide a valve seat 7, Between that valve stem 3 and the valve cov 2 there is provided a packing assembly 9, An O-ring 10 is further dispose at that upper portion of the packing assembly 9, An upper part of that O-ring 10 is provide with a packing gland 11, The valve body 1 is provided with an arc-shaped end face 12, the arc-shaped end face 12 forms a line seal between the valve body 1 and the valve seat 7, the contact end of the valve disc 4 and the valve seat 7 is provided with a water grain surface 41, the packing assembly 9 comprises a flexible graphite packing layer, the valve body 1 is provided with a liquid inlet cavity and a liquid outlet cavity, the two O-rings 10 are concentric arranged, and the inner diameter and outer diameter of the two O-rings are different.准提道人，真不如他明朝正德年间，连中两元的唐伯虎被苏州百姓寄予厚望，人人都看好他考取状元衣锦还乡。然而，进京赶考的他受到考场舞弊案的牵连，一夕间从状元郎变成阶下囚。幸得皇帝惜才，唐伯虎拣回一命，却是此生再与功名无缘。回到苏州后的唐伯虎从此不问仕途，专心书画，与民同乐，并吸引不少同道中人，与性格迥异的祝枝山、文徵明、徐祯卿三人一起以智斗恶，为民除害，惩治贪官恶霸，并不懈追求各自的爱情，结为倍受百姓喜爱的“江南四大才子“。托德·施特劳斯-斯古尔森将执导新线影业新片[难道不浪漫](Isn’t It Romantic,暂译)。影片由蕾蓓尔·威尔森主演，讲述一位刻薄女孩的平凡生活一夜之间变作了充满浪漫的爱情喜剧，她也由此成为朋友们的话题中心。斯古尔森以拍摄喜剧见长，2015年他导演的[幸存的女孩]曾入围多伦多电影节。
