CWE-415
Double Free
The product calls free() twice on the same memory address.
Mitigation
Phase: Architecture and Design
Description:
- Choose a language that provides automatic memory management.
Mitigation
Phase: Implementation
Description:
- Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Phase: Implementation
Description:
- Use a static analysis tool to find double free instances.
