Debian DLA-2692-1 : bluez - LTS security update

medium Nessus Plugin ID 151044

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2692 advisory.

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 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

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

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

Solution

Upgrade the bluez packages.

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