Debian LTS Advisory DLA-2692-1 [email protected]
https://www.debian.org/lts/security/ Thorsten Alteholz

Package : bluez
Version : 5.43-2+deb9u4
CVE ID : CVE-2020-26558 CVE-2021-0129

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
