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...
return-into-libcreturn-oriented programmingturingcompleteSummary: Return-into-libc (RILC) is one of the most common forms of code-reuse attacks. In this attack, an intruder uses a buffer overflow or other exploit to redirect control flow through existing (libc) functions within the legitimate ...
there exists a variant of buffer-overflow attack called the return-to-libc attack, which does not need an executable stack; it does not even use shell code. Instead, it causes the vulnerable programto jump to some existing code, such as the system() function in the libc library, which...
