CVE-2019-13179 (opens in a new tab)How to fix?
Upgrade Debian:11 calamares to version 3.2.11-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream calamares package and not the calamares package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
Calamares versions 3.1 through 3.2.10 copies a LUKS encryption keyfile from /crypto_keyfile.bin (mode 0600 owned by root) to /boot within a globally readable initramfs image with insecure permissions, which allows this originally protected file to be read by any user, thereby disclosing decryption keys for LUKS containers created with Full Disk Encryption.
