BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, a malformed but non-empty BACnet WriteProperty request can drive the official server demo into a non-terminating request-processing loop with repeated heap-backed side effects. This results in a remote unauthenticated denial of service via uncontrolled resource consumption and a non-terminating request path. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.
