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:
