A user may be tricked into opening a malicious FBX file which may exploit a use-after-free vulnerability in FBXs Review causing the application to reference a memory location controlled by an unauthorized third party, thereby running arbitrary code on the system.

Weakness

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
