Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the rpm_decode_object_property process. An attacker can cause the application to read memory past allocated buffer boundaries and potentially crash the system by sending a crafted BACnet/IP packet with a truncated property list containing an extended tag marker. This is only exploitable if the ReadPropertyMultiple confirmed service handler is enabled.
