Buffer overflow 定义 Buffer overflow is defined as the condition in which a program attempts to write data beyond the boundaries of pre-allocated fixed length buffers. 缓冲区溢出存在的问题 This vulnerability can be utilized by a malicious user to alter the flow control of the program, even...
Format String Vulnerability Lab——格式化字符串漏洞 1 实验概述 格式化字符串漏洞是由像printf(user_input)之类代码引起的,这里user_input变量的内容由用户提供。当这个程序由特权运行(例如Set-UID程序),这个printf会导致以下情况之一: (1)程序崩溃; (2)从内存任意位置读取; (3)修改任意内存位置的值。 应该注意,...

For the buffer overflow vulnerability you've found, construct an input to send to the touchstone web server, your goal is to crash the web server (the http server daemon). Note: if you're successful to crash the web server, your browser will remain dead-waiting to receive data from the...
把数据写在固定长度的缓冲区的外面, 但是程序在向缓冲区内写入数据时没有得到良好的保护, 自己程序的栈结构就会被缓冲区外的数据破坏, 这些数据中如果有 "不...
which helps avoid buffer overflows. Polyspace Bug Finder provides various checkers that not only identify buffer overflow issues, but also other potential constructs that can lead to and exploit a buffer overflow vulnerability. This early and quick feedback enables the development teams to address suc...
the server by buffer overflows, pay special attention to the fileparse.c. Write down a description of each vulnerability in the file named bugs.txt. Note: For each vulnerability, how you would construct the input (i.e., the HTTP request) to overflow the buffer, ...
