What is a 'buffer overflow' attack and how can it be prevented in coding?
- Allocating excessive memory for a buffer
- Ignoring buffer constraints during coding
- Limiting input size to buffer capacity
- Overflowing a buffer to execute malicious code
A buffer overflow occurs when a program writes more data to a buffer than it can hold, potentially leading to the execution of malicious code. To prevent buffer overflow attacks in coding, developers should implement measures such as input validation, bounds checking, and using secure coding practices. By validating and limiting input sizes to match buffer capacities, developers can mitigate the risk of buffer overflows and enhance the security of their code.__________________________________________________
