Research buffer overflow attacks and develop a timeline of major attacks. Comment on why the buffer overflow vulnerability still exists

Expert Solution

First of all, let's discuss in brief, what is this Buffer Overflow?

It is an anomaly that occurs when the data to a buffer overflows the buffer’s capacity, resulting in adjacent memory locations being overwritten.
We can also say like, too much information is being passed into a container that does not have enough space.,

Now, when hackers or people with wrong intentions exploit this thing, it is called Buffer Overflow Attack.

Common timeline of these attacks:

1988: Robert Morris's Internet Worm: overflow in fingered
2001: Code Red: overflow in ISS
2003: Slammer: Overflow in Microsoft SQL server 2000
2004: Buffer Overrun in JPEG Processing (GDI+) Could Allow Code Execution
2006: In Adobe Acrobat
2007: Vulnerability in Windows Animated Cursor Handling
2008: RealNetworks RealPlayer ’rmoc3260.dll’ ActiveX Control Memory Corruption
2009: Operation Aurora: Zero-day vulnerabilities in IE

There are numerous of Buffer Overflow attacks happened in history on various systems. Few of the very high-profile affected systems are(Many important details about these systems are not publically available):

Many famous VPN products. Exact product: Unknown
NVIDIA SHIELD TV
macOS Catalina
Chat Messanger applications

There are many reasons why the buffer overflow vulnerability still exists. The most important among them are as follows:

Still, few languages are not very capable in every aspect. Like C and C++ still don’t have built-in safeguards against overwriting or accessing data in their memory. And as we all know Linux, Windows, macOS all uses C and C++.
Due to dependency on external applications. It is not always possible to write everything from scratch and due to this dependencies, these type of vulnerability may arise as we can't fully control the implementation of external applications.

1.write three methods to exploit buffer overflow and to archive the goal. If local variables are exploited present all possible approaches. Goal: The goal is to exploit the program to let it print out “CORRECT SERIAL”. Note: A “Segmentation fault” is fine if the program prints out the desired message. C programming

I am exploiting a buffer overflow attack and need to find three pieces of information in Linux using gdb. 1) The address of the function system 2) The address of the function parameter for system() which is /bin/sh. /bin/ parameter is what will spawn a shell 3) The address of a function that can exit the shell. I was able to use gbd commands to find the first two but what command would I use to find the address of...
