CVE-2021-40528

Una implementación de ElGamal en Libgcrypt versiones anteriores a 1.9.4, permite una recuperación de texto plano porque, durante la interacción entre dos bibliotecas criptográficas, una determinada combinación peligrosa del primo definido por la clave pública del receptor, el generador definido por la clave pública del receptor y los exponentes efímeros del emisor puede conllevar a un ataque de configuración cruzada contra OpenPGP.

A flaw was found in libgcrypt's ElGamal implementation, where it allows plain text recovery. During the interaction between two cryptographic libraries, a certain combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP. The highest threat from this vulnerability is to confidentiality.
