CVE-2023-0751: GELI silently omits the keyfile if read from stdin
First published: Wed Feb 08 2023(Updated: )
When GELI reads a key file from standard input, it does not reuse the key file to initialize multiple providers at once resulting in the second and subsequent devices silently using a NULL key as the user key file. If a user only uses a key file without a user passphrase, the master key is encrypted with an empty key file allowing trivial recovery of the master key.
