Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2020-26558, CVE-2021-0129.
More information:

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.
