Which vulnerability type is addressed by PCI DSS Requirement 6.5.2?

• A. Insecure cryptographic storage
• B. Buffer overflows
• C. Insecure communications
• D. Improper error handling

Answer: (B)

The idea here is that this PCI DSS requirement focuses on secure coding practices in the software development process to prevent memory-safety vulnerabilities. Buffer overflows are a classic example of such issues: when a program writes more data into a memory buffer than it can hold, it can corrupt memory, crash, or allow arbitrary code execution. Requirement 6.5.2 calls for addressing these kinds of vulnerabilities through secure coding standards, input validation, proper bounds checking, the use of safe libraries or languages, and thorough code reviews and testing before software is released. This focus on preventing coding flaws that enable memory corruption is the reason it’s the best fit. Other vulnerability types like insecure cryptographic storage, insecure communications, or improper error handling are tackled under different controls and areas of PCI DSS.
