Weaknesses
CWE · root cause- CWE-244Improper Clearing of Heap Memory Before Release ('Heap Inspection')Using realloc() to resize buffers that store sensitive information can leave the sensitive information exposed to attack, because it is not removed from memory.
- CWE-212Improper Removal of Sensitive Information Before Storage or TransferThe product stores, transfers, or shares a resource that contains sensitive information, but it does not properly remove that information before the product makes the resource available to unauthorized actors.
