Debian DSA-5584-1 : bluez - security update

medium Nessus Plugin ID 187196

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5584 advisory.

 - Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of HID messages when no user interaction has occurred in the Central role to authorize such access. An example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556 mitigation would have already addressed this Bluetooth HID Hosts issue. (CVE-2023-45866)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the bluez packages.

For the stable distribution (bookworm), this problem has been fixed in version 5.66-1+deb12u1.
