Return-to-libc Attack 学习目标是获得关于缓冲区攻击的有趣变种的一手体验;此攻击可以绕过当前在主要Linux操作系统中实现的现有保护方案。利用缓冲区过度漏洞的常见方法是使用恶意shellcode将缓冲区过度流动,然后导致易受攻击的程序跳转到存储在堆栈中的shellcode。为防止这些类型的攻击,一些操作系统允许系统管理员使堆栈...
The learning objective of this lab is for students to gain the firsthand experience on an interesting variantof buffer-overflow attack; this attack can bypass an existing protection scheme currently implemented inmajor Linux operating systems. A common way to exploit a buffer-overflow vulnerability is...
Return to Libc attack solution and explanation for seed lab Setup: Ubuntu and several other Linux-based systems use address space randomization to randomize the starting address of heap and stack, making guessing the exact addresses difficult.
