ABC喜剧《格尔伯格一家 The Goldbergs》曾经在16年开发衍生剧但没获预订，而电视网在美国时间1月24日放出拍好的试映集后（S05E00 「1990 Something」那集），倒是因为反应良好令ABC决定改变主意预订该衍生剧，现定于19年1月9日首播，由《格尔伯格一家》前导。暂定13集的《校园时代 Schooled》定于90年代，主角包括Glascott校长﹑Mellor教练及Lainey Lewis（Tim Meadows﹑Bryan Callen及AJ Michalka饰演），他们虽然有怪癖﹑个人生活有点疯狂，但仍然是学生们心目中的英雄。Brett Dier饰演C.B.，此角色是改编自母剧主创Adam F. Goldberg的老师兼朋友，C.B.是名年轻﹑活跃的老师，在课堂上以滑稽的方式与学生互动，他亦是菜鸟老师Lainey Lewis的朋友/对手。衍生剧原构念是复制《格尔伯格一家》的家庭喜剧模式，后来改为注重在校园喜剧这方向，新增了母剧的Lainey Lewis一角。

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.
