Debian 9 Stretch DLA-2692-1: Bluez Critical Issues and Fixes

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.
