What is BUFFER OVERFLOW? What does BUFFER OVERFLOW mean? BUFFER OVERFLOW meaning & explanation

What is BUFFER OVERFLOW? What does BUFFER OVERFLOW mean? BUFFER OVERFLOW meaning - BUFFER OVERFLOW definition - BUFFER OVERFLOW explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In computer security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations. Buffers are areas of memory set aside to hold data, often while moving it from one section of a program to another, or between programs. Buffer overflows can often be triggered by malformed inputs; if one assumes all inputs will be smaller than a certain size and the buffer is created to be that size, if an anomalous transaction produces more data it could cause it to write past the end of the buffer. If this overwrites adjacent data or executable code, this may result in erratic program behavior, including memory access errors, incorrect results, and crashes. Exploiting the behavior of a buffer overflow is a well-known security exploit. On many systems, the memory layout of a program, or the system as a whole, is well defined. By sending in data designed to cause a buffer overflow, it is possible to write into areas known to hold executable code, and replace it with malicious code. Buffers are widespread in operating system (OS) code, so it is possible to make attacks that perform privilege escalation and gain unlimited access to the computer's resources. The famed Morris worm used this as one of its attack techniques. Programming languages commonly associated with buffer overflows include C and C++, which provide no built-in protection against accessing or overwriting data in any part of memory and do not automatically check that data written to an array (the built-in buffer type) is within the boundaries of that array. Bounds checking can prevent buffer overflows, but requires additional code and processing time. Modern operating systems use a variety of techniques to combat malicious buffer overflows, notably by randomizing the layout of memory, or deliberately leaving space between buffers and looking for actions that write into those areas ("canaries").

How to exploit a buffer overflow vulnerability - Practical
 
09:44
This tutorial goes over the basic technique of how to exploit a buffer overflow vulnerability with an example. This tutorial assumes that you already have: basic C knowledge, gdb, gcc and how programs represent memory. The source code for the program can be downloaded at https://drive.google.com/file/d/0B8b0M2LATseXYWRiVHdkaGhwRjg/view?usp=sharing The 46 byte shellcode used in this program is "\x31\xc0\xb0\x46\x31\xdb\x31\xc9\xcd\x80\xeb\x16\x5b\x31\xc0\x88\x43\x07\x89\x5b\x08\x89\x43\x0c\xb0\x0b\x8d\x4b\x08\x8d\x53\x0c\xcd\x80\xe8\xe5\xff\xff\xff\x2f\x62\x69\x6e\x2f\x73\x68" The compiling line is gcc -o example -fno-stack-protector -m32 -z execstack example.c -fno-stack-protector === Removes the canary value at the end of the buffer -m32 === Sets the program to compile into a 32 bit program -z execstack === Makes the stack executable NOTE: If this tutorial is not working it is likely that you have aslr enabled. To disable it run the following command in your terminal echo 0 | sudo tee /proc/sys/kernel/randomize_va_space When you are finished I strongly recommend you turn it back on with the command echo 2 | sudo tee /proc/sys/kernel/randomize_va_space

We will consider important software vulnerabilities and attacks that exploit them -- such as buffer overflows, SQL injection, and session hijacking -- and we will consider defenses that prevent or mitigate these attacks, including advanced testing and program analysis techniques. Importantly, we take a "build security in" mentality, considering techniques at each phase of the development cycle that can be used to strengthen the security of software systems. Successful learners in this course typically have completed sophomore/junior-level undergraduate work in a technical field, have some familiarity with programming, ideally in C/C++ and one other "managed" program language (like ML or Java), and have prior exposure to algorithms. Students not familiar with these languages but with others can improve their skills through online web tutorials.

Network Security – Buffer Overflow
 
14:29
Course 3 - Hacking and Patching About this course: In this MOOC, you will learn how to hack web apps with command injection vulnerabilities in a web site of your AWS Linux instance. You will learn how to search valuable information on a typical Linux systems with LAMP services, and deposit and hide Trojans for future exploitation. You will learn how to patch these web apps with input validation using regular expression. You will learn a security design pattern to avoid introducing injection vulnerabilities by input validation and replacing generic system calls with specific function calls. You will learn how to hack web apps with SQL injection vulnerabilities and retrieve user profile information and passwords. You will learn how to patch them with input validation and SQL parameter binding. You will learn the hacking methodology, Nessus tool for scanning vulnerabilities, Kali Linux for penetration testing, and Metasploit Framework for gaining access to vulnerable Windows Systems, deploying keylogger, and perform Remote VNC server injection. You will learn security in memory systems and virtual memory layout, and understand buffer overflow attacks and their defenses. You will learn how to clone a Kali instance with AWS P2 GPU support and perform hashcat password cracking using dictionary attacks and known pattern mask attacks. Who is this class for: Any one interested in learning how to hack and patch web apps with injection vulnerabilities, crack passwords on AWS P2 system, system security design pattern using hand-on labs, quick introduction to buffer overflow, Nessus scanning tool and Kali Penetration Testing suite. The needs to know how to program in a high level programming language. Module 3 - Memory Attacks and Defenses In this module, we learn about the typical protection mechanism provided by the modern OS to prevent process from accessing other pages data belong different process. We will also learn buffer overflow attacks and their common defenses. Learning Objectives • By the end of this course, you should be able to understand buffer overflow attacks and deploy their defenses. • By the end of this module, you can understand how the buffer overflow occurs. • By the end of this module, understand how turn off stack execution and adding canar pattern to calling stack can prevent buffer overflow from happening.

We will consider important software vulnerabilities and attacks that exploit them -- such as buffer overflows, SQL injection, and session hijacking -- and we will consider defenses that prevent or mitigate these attacks, including advanced testing and program analysis techniques. Importantly, we take a "build security in" mentality, considering techniques at each phase of the development cycle that can be used to strengthen the security of software systems. Successful learners in this course typically have completed sophomore/junior-level undergraduate work in a technical field, have some familiarity with programming, ideally in C/C++ and one other "managed" program language (like ML or Java), and have prior exposure to algorithms. Students not familiar with these languages but with others can improve their skills through online web tutorials.
