Weaknesses (CWE)
CWE-122 — Heap-based Buffer Overflow: A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
- Pre-design: Use a language or compiler that performs automatic bounds checking.
- [Architecture and Design] Use an abstraction library to abstract away risky APIs. Not a complete solution.
