Buffer overflow is a software coding error that enables hackers to exploit vulnerabilities, steal data, and gain unauthorized access to corporate systems. Discover what is a buffer overflow attack and how Fortinet can mitigate and prevent overflow attack
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. Bu...
A buffer overflow attack can be: Stack-based.Your attacker sends data to a program, and that transmission is stored in a too-small stack buffer. Your hacker could choose a "push" function and store new items on the top of the stack. Or the hacker could choose a "pop" function and re...
Sometimes a vulnerability slips through the cracks, remaining open to attack despite controls in place at the development, compiler, or operating system level. Sometimes, the first indication that a buffer overflow is present can be a successful exploitation. In this situation, there are two critica...
