Buffer Overflow Attack 缓冲区溢出定义为程序尝试将数据写入超出预分配的固定长度缓冲区边界的情况。恶意用户可以利用此漏洞来更改程序的流控制,甚至执行任意代码段。这个漏洞是由于数据存储(例如缓冲区)和控件存储(例如返回地址)的混合而产生的:数据部分的溢出会影响程序的控制流,因为溢出会改变返回地址。 在本实验中,...

The above is an example code for performing buffer overflow attack, it works when compiled using clang , but not when compiled using gcc. I think the problem is than of array alignment. On using the compile flag -mpreferred-stack-boundary=2 the program do works in gcc. B...
buffer overflow attack 思路:通过输入的字符串,利用缓冲区溢出,改变getbuf()函数活动记录的返回地址为getbuf[0]所在地址,即是输入的二进制机器代码,机器代码使返回值所在eax寄存器中的值变为DEADBEEF, 并返回到程序正常返回的地址。 步骤: 1.首先查看buf地址 2.查看原始ebp的内容,可以通过buf[15]地址加上1个...
黑客入门 - Buffer overflow attack (堆栈溢出攻击) 最近做了一个buffer overflow的mini-project,用ssh登陆一个本地的virtualBox运行的Linux,利用buffer overflow获取root权限。详细过程请观看视频。 参考论文 - Smashing The Stack For Fun And Profit 内存layout: 黑客入门 - 堆栈溢出攻击 (buffer overflow attack)....
内容提示: 缓冲区溢出攻击(buffer overflow attack) Buffer overflow is a very common and very dangerous vulnerability. It is widely used in various operating systems and Applications . The use of buffer overflow attacks, can cause the program failed, system crashes, restart the consequences. What is...
I have a buffer overflow lab I have to do for a project called The Attack Lab. I'm on phase 2 of the lab, and I have to inject code as part of my exploit string in order to make the program point to the address of the function touch2(). I've gotten to the point where the...
