Multiple can hit the head, but it really doesn't start automatically.Since the public's awareness of environmental protection awakened, the word garbage classification has gradually entered our life. In the past ten years or so, what has been the progress of garbage classification and has it kept pace with the times? There is a long way to go to sort out garbage, but it is also searching up and down. Waste collectors who graduated from the Chinese Academy of Sciences have done something big. They have to sweep the code for garbage collection. Is this reliable? This week, we sneaked into the streets and listened to what everyone said.电影《最普通的恋爱》将是一部浪漫喜剧,讲述30代男女间的现实爱情,将于今年冬季进行拍摄,预计将于2019年下半年于韩国上映。黄胖子将迷信的部分压制住，突出吉利与风气，措辞相当的智慧。几位已婚男性好友，决心杀掉其中一位的“恶魔”妻子。沃德的太太，大家——包括沃德本人在内——一致公认，是个可恶的暴君，恶魔的化身。沃德的几位好友，在多次半开玩笑地谈话之后，制定了一个计划，打算要她的命——虽然实施过程有些意外，但磕磕绊绊终于成功了。下一步便是如何不留痕迹地处理掉尸体。虽然其中涉及谋杀、肢解等血淋淋的情节，但由于几位好友都是彻头彻尾的“外行”，整个过程却又诡异地笑料百出。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.
