Free CompTIA Security+ SY0-601 Practice Question
When developing an application, a programmer must carefully manage the resources to prevent security vulnerabilities. Which of the following scenarios represents the BEST example of an integer overflow that could result in security implications?
A database uses a long integer type to auto-increment primary keys to prevent running out of unique identifiers.
A cryptographic algorithm uses large prime numbers for generating keys, ensuring secure communication between parties.
A function that improperly validates user input allows a very large value to be submitted, causing the program to wrap the integer count and overwrite adjacent memory.
A user is denied file upload capabilities after reaching the upload limit, preventing any further data from being added to the server.
A payment application prompts the user when the inputted credit card number exceeds the standard length and awaits correct input.
