从上面的例子中不难看出,我们可以通过Buffer Overflow来改变在堆栈中存放的过程返回地址,从而改变整个程序的流程,使它转向任何我们想要它去的地方.这就为黑客们提供了可乘之机, 最常见的方法是: 在长字符串中嵌入一段代码,并将过程的返回地址覆盖为这段代码的地址, 这样当过程返回时,程序就转而开始执行这段我们自...

But do you know that there is a possibility of buffer overflow in this program. The gets() function does not check the array bounds and can even write string of length greater than the size of the buffer to which the string is written. Now, can you even imagine what can an attacker d...
So now we know that there is an overflow and, more importantly, that the overflow is exploitable.Now what I want to do is overflow the stack and call bar().So the first thing I need to do is figure out where the overflow happens at. How many ‘A’s do we need to pump in to ...
A stack buffer overflow can happen many ways in C or C++. We provide several examples for this category of error that you can catch by a simple recompile.Example - stack buffer overflowC++ Copy // example1.cpp // stack-buffer-overflow error #include <string.h> int main(int argc, ...

In information security and programming, a buffer overflow, also known as a buffer overrun, is a software coding vulnerability or error that cybercriminals can abuse to obtain unauthorized access to a company’s system. The software error focuses on buffers, which are areas of memory that ...
C language is still important as a programming language of softwares such as network control software that needs high security. But the buffer-overflow problem is frequently seen in C programs, it is one of the most serious vulnerabilities about C programs. Among the buffer-overflow vulnerabilities...
