Hi,

The following vulnerabilities were published for bluez.

CVE-2021-0129[0], and

CVE-2020-26558[1]:
| Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification
| 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to
| identify the Passkey used during pairing (in the Passkey
| authentication procedure) by reflection of the public key and the
| authentication evidence of the initiating device, potentially
| permitting this attacker to complete authenticated pairing with the
| responding device using the correct Passkey for the pairing session.
| The attack methodology determines the Passkey value one bit at a time.


If you fix the vulnerabilities please also make sure to include the
CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
