Debian DLA-2692-1 : bluez security update

medium Nessus Plugin ID 151044

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Two issues have been found in bluez, a package with Bluetooth tools and daemons. One issue is about a man-in-the-middle attack during secure pairing, the other is about information disclosure due to improper access control.

In order to completely fix both issues, you need an updated kernel as well! For Debian 9 Stretch this has been uploaded some days ago.

For Debian 9 stretch, these problems have been fixed in version 5.43-2+deb9u4.

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

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
