  script_tag(name:"insight", value:"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: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
