CVE-2017-9079 (opens in a new tab)How to fix?
Upgrade Debian:11 dropbear to version 2016.74-5 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream dropbear package and not the dropbear package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
Dropbear before 2017.75 might allow local users to read certain files as root, if the file has the authorized_keys file format with a command= option. This occurs because ~/.ssh/authorized_keys is read with root privileges and symlinks are followed.
