Name of the Vulnerable Software and Affected Versions openssl encrypt versions prior to 1.4.9
Description The D-Bus CryptoService.EncryptFile handler uses unstretched SHA-256 instead of Argon2id for key derivation. This allows attackers to perform offline password guessing against encrypted files significantly faster than the documented protection by exploiting the absence of key stretching and hash rounds.
Recommendations Update to version 1.4.9 or later.
