Two vulnerabilities in new Bluetooth chip, dubbed BLEEDINGBIT expose millions of access points and other networking devices to remote attacks. The issues affect Bluetooth Low Energy (Bluetooth 4.0) chips that are designed for applications that do not require exchanging large amounts of data, such as smart objects in healthcare and sports.
