Continuous assessment - Rectification of program vulnerabilities 

Write program segments to illustrate the following:

1. A code that allows an attacker to cause stack smashing

2. A code that does not perform range checking

3. A code that allows an attacker to cause variables to overflow and exploit adjacent variables

4. A code that allows an attacker to execute a malicious code by exploiting a pointer variable

5. A code that rectifies the above issues by implementing the following:

* Canary

* Bounds checking

* Tagging

6. A code segment in a web page that allows an attacker to use SQL injection

7. A code segment in a web page that prevents an attacker to use SQL injection
