Machine-written summary

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

openssl-encrypt versions up to and including 1.4.8 do not sanitize filenames read from untrusted drive data before printing them in the verify-usb command's output. An attacker who can place files on a drive that a user checks can embed terminal control sequences in the filenames, which can repaint a forged PASSED result on screen and hide tamper detection. Upgrade to version 1.4.9, which sanitizes these names before display.
