📋 Description

Microsoft is aware of the Bluetooth Forward and Future Secrecy Attacks and Defenses (BLUFFS) vulnerability. For more information regarding the vulnerability, please see this statement from the Bluetooth SIG. To address the vulnerability, Microsoft has released a software update that enforces the use of BR/EDR Secure Connections defined encryption and authentication algorithms for Bluetooth pairings that have used BR/EDR Secure Connections. If a paired device used BR/EDR Secure Connection at some point, Windows will enforce all subsequent BR/EDR connections to use BR/EDR Secure Connections. As defined by the BR/EDR Secure Connections protocol, the new BR/EDR Secure Connections algorithms will only be used when the local system and the remote paired device both support BR/EDR Secure Connections. Connections between the local system and the remote paired device will remain vulnerable if either the local system or the remote paired device never declare support for BR/EDR Secure Connections during encryption or authentication.. Additionally, it is advised to increase the minimum encryption key size as described in Windows guidance for Bluetooth key length enforcement. Increasing the minimum encryption key size does not require support for BR/EDR Secure Connections.
