GSEC · Question #237
Which of the following statements about buffer overflow is true?
The correct answer is C. It is a condition in which an application receives more data than it is configured to accept. A buffer overflow occurs when an application receives more input data than its allocated memory buffer can hold, potentially causing crashes or enabling code execution attacks.

Why each option
A buffer overflow occurs when an application receives more input data than its allocated memory buffer can hold, potentially causing crashes or enabling code execution attacks.
Managing security credentials and public keys describes a Public Key Infrastructure (PKI) or key management system, not a buffer overflow.
A collection of Microsoft update files released between major service packs describes a hotfix rollup or update bundle, not a buffer overflow.
A buffer overflow is precisely defined as the condition where an application receives more data than it is configured or allocated to handle. When the input exceeds the buffer boundary, it overwrites adjacent memory, which attackers can exploit to execute arbitrary code or crash the application.
A false warning about a virus describes a virus hoax, which is a social engineering tactic unrelated to buffer overflows.
