What the vulnerability does

01Description

openssl_encrypt versions before 1.4.9 fail to sanitize recovery-slot metadata in the desktop GUI, allowing attackers to inject control characters and line separators into the irreversible-removal confirmation dialog. Attackers can craft encrypted files with malicious slot identifiers containing bidi overrides or line-separator characters to forge warning text and deceive users during file removal operations.
