Prior to versions 1.4.5, 1.5.1, and 1.6.0, a Denial of Service (DoS) vulnerability exists in the BACnet stack's ReadPropertyMultiple (RPM) handler. When processing a malformed RPM request packet that lacks the expected closing tags, the function handler_read_property_multiple enters an infinite loop.
