Academic research on vulnerable c++ code snippet

[JafarAkhondali]

Dear BhallaLab, We are a group of Academic researchers. We are analyzing vulnerable C++ code snippets migrated from StackOverflow to GitHub. Our research will be published in Academic publications and will not be used in any Industrial application. We noted a vulnerable code snippet in your repository that was most likely copied from Stack Overflow. The vulnerability exists in this source code file of your repository.

Please verify our report here with regards to the above vulnerability to assist you. Link to report with four questions for you related to the vulnerability (should not take more than 5 minutes to answer).

Here is a summary of the vulnerable code snippet:

Description:

• rand() is an obsoleto function and used most in c.
• rand() % mod is not good practice since it'll use lower bits which are not so random.

Mitigation:

• Best mitigation is to use another method instead of rand(), like this answer
