Brief description (purpose and overview)
Buffer vulnerability is one of the top and most destructive vulnerabilities. In this lab, you will gain further understanding of the buffer overflow vulnerability by writing the vulnerable code and exploit code, and conducting attacks. We will use a well designed lab developed by Prof. Wenliang Du from Syracuse University. 

Learning Objectives
After finishing this lab, students shall be able to: 
1.    Understand basic concepts about buffer overflow attack
2.    Understand memory layout and suid problems.
3.    Write basic exploit code and perform attacks.
Prerequisite knowledge
●    Have very basic knowledge of C
●    Be comfortable using a CLI and gcc .
Lab Setup Requirements
●    Download and Install prebuilt ubuntu 16.04 VM from the SEED website  (http://www.cis.syr.edu/~wedu/seed/labs.html )
Detailed instructions
Please refer to the lab description posted on the SEED lab page. (https://seedsecuritylabs.org/Labs_16.04/Software/Buffer_Overflow/)
Questions
