Descriptions

lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto's ElGamal implementation.

lib/Crypto/PublicKey/ElGamal.py en PyCrypto hasta la versión 2.6.1 genera parámetros de clave ElGamal débiles, lo que permite que atacantes remotos obtengan información sensible mediante la lectura de datos en texto cifrado (p.ej., no tiene seguridad semántica a la hora de enfrentarse a un ataque solo en texto cifrado). La hipótesis DDH (Decisional Diffie-Hellman) no soporta la implementación ElGamal de PyCrypto.
