Hello, Josh, Steve, vendors, It was found that D-BUS message bus service / messaging facility did not update the byte-order flag of the message properly by swapping the byte order of incoming messages into their native endiannes. A local, authenticated user could use this flaw to send a specially-crafted message to a system service (like Avahi or NetworkManager), using the system bus, potentially leading to disconnect of such a service from system bus (denial of service).
