Ubuntu Security Notice 6742-1 - Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials. A physically proximate attacker placed between two Bluetooth devices could use this to subsequently impersonate one of the paired devices. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
