Description
BACnet Stack is a BACnet open source protocol stack C library for embedded systems. From versions 1.4.0 to before 1.4.4, and 1.5.0 to before 1.5.1, a NULL pointer dereference can be triggered in bacnet_device_object_reference_decode() when a WriteProperty request updates OBJECT_STRUCTURED_VIEW / PROP_SUBORDINATE_LIST. This issue has been patched in versions 1.4.4 and 1.5.1.
