Machine-written summary

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

openssl-encrypt versions before 1.4.9 do not sanitize recovery-slot metadata in the desktop GUI, so control characters and line separators can reach the irreversible-removal confirmation dialog. An attacker who crafts an encrypted file with malicious slot identifiers can forge the warning text and mislead a user during file removal. Upgrade to version 1.4.9 or later.
