Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the wpm_decode_object_property process calling the deprecated decode_tag_number_and_value function. An attacker can cause the application to read past allocated buffer boundaries, potentially leading to crashes or disclosure of sensitive information, by sending a crafted BACnet/IP packet with a truncated property payload.
