Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 / 23.10 : BlueZ vulnerability (USN-6540-1)

medium Nessus Plugin ID 186644

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6540-1 advisory.

 It was discovered that BlueZ did not properly restrict non-bonded devices from injecting HID events into the input subsystem. This could allow a physically proximate attacker to inject keystrokes and execute arbitrary commands whilst the device is discoverable.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
