Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of openssl-encrypt up to and including 1.4.8 advertise a portable USB workspace as encrypted, but files placed in it are stored in cleartext because the derived key is never applied. Anyone with physical access to the USB media can read those files, though this requires the user to rely on the workspace for protection. Upgrade to version 1.4.9, which encrypts the workspace in an authenticated AES-256-GCM vault.
