CWE-119 CWE-416

> CWE DETAILED DESCRIPTIONS

CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer - The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. | CWE-416: Use After Free - The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
