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,...

A common stack overflow exploit is to change the value of RETADDR and store the address of the attack code injected into the stack or the addresses of some privileged system functions in the code area to RETADDR. If the value of RETADDR is changed, after the function is called, the program...

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...
typically under the control of an attacker who wishes to take control of the program, or at least influence its execution. Typically (but not necessarily), such overflow data include code that is executed as part of an attack. Buffer overflows can also occur over the network. Buffer overflow...
