 Package : bluez Version : 5.50-1.2~deb10u4 CVE ID : CVE-2023-45866 Debian Bug : 1057914

 It was discovered that there was a keyboard injection attack in Bluez, a set of services and tools for interacting with wireless Bluetooth devices.

 Prior to this change, BlueZ may have permitted an unauthenticated peripherals to establish encrypted connections and thereby accept keyboard reports, potentially permitting injection of HID (~keyboard) commands, despite no user authorising such access.

 For Debian 10 buster, this problem has been fixed in version 5.50-1.2~deb10u4.

 We recommend that you upgrade your bluez packages.

 For the detailed security status of bluez please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/bluez

Solution

Upgrade the bluetooth packages.
