MEDIUM

FreeBSD - Improper Input Validation in GELI Key File Handling

Title source: llm
STIX 2.1

Description

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.
