Mitigation
Phase: Implementation
Description:
- Only call matching memory management functions. Do not mix and match routines. For example, when you allocate a buffer with malloc(), dispose of the original pointer with free().
Mitigation
Phase: Implementation
Description:
- When programming in C++, consider using smart pointers provided by the boost library to help correctly and consistently manage memory.
Mitigation ID: MIT-4.6
Phase: Architecture and Design
Strategy: Libraries or Frameworks
Description:
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, glibc in Linux provides protection against free of invalid pointers.
Mitigation
Phase: Architecture and Design
Description:
- Use a language that provides abstractions for memory allocation and deallocation.
Mitigation
Phase: Testing
Description:
- Use a tool that dynamically detects memory management problems, such as valgrind.
