seed实验——Set-UID Program Vulnerability实验 一、实验描述 Set-UID是Unix OS中的一个·非常重要的安全机制。当一个Set-UID程序运行的时候,它具有代码拥有者的权限。举个例子,如果代码的拥有者是root用户,那么不论任何用户运行该程序时,程序都能以root用户的权限运行。Set-UID可以做许多有趣的事情,但也很不幸,...
计算机安全_Lab1_Set-UID Program Vulnerability(YUE) :1.建立一个动态链接库。把下面的程序命名为mylib.c。在函数库libc中重载了sleep函数。2.编译mylib.c3.编写myprog.c4.在普通用户编译myprog.c并...实现它。 (2)注意其不好的一面:了解其潜在的安全问题。2实验内容 2.1 task1实验任务:弄清楚为什么“passw...
本来test.c对seed用户是不可写的,但因为task8是SET-UID程序,且时root权限,因此可以删除test.c文件。由此可得出结论:set-UID程序是非常危险的。 实验过程二:注释掉system(command)语句,并取消注释execve()语句;程序将使用execve()来调用命令。编译程序,并使其成为Set-UID程序。那么在步骤一中的攻击是否仍然有效? ...
I have some questions regarding the documentation at https://readthedocs.org/projects/pyinstaller/downloads/pdf/stable/, which currently states the following: Do not give administrator privileges to a one-file executable (setuid root in ...
由于key不能重复，所以，在set中，没有重复的key。 集合是一个无序的，不重复的数据组合，它的主要作用如下： 去重，把一个列表变成集合，就自动去重了 关系测试，测试两组数据之前的交集、差集、并集等关系 集合(set)：把不同的元素组成一起形成集合，是python基本的数据类型。 集合元素(set elements):组成集合...
