CVE-2020-7084

Application crash via crafted FBX null dereference

Published Apr 17, 2020 · Updated Aug 4, 2024

NULL pointer dereference in Autodesk FBX SDK 2019.5 and earlier allows attackers to crash an application by opening a malicious FBX file. The SDK's FBX parser dereferences a null pointer while processing the crafted file, but Autodesk has not disclosed the affected function or malformed field. Exploitation requires a user or consuming service to process the file and causes only the hosting application to crash.
