CWE-325
Bugzilla:
1542313: CVE-2018-6594 python-crypto: Weak ElGamal key parameters in PublicKey/ElGamal.py allow attackers to obtain sensitive information by reading ciphertext

The MITRE CVE dictionary describes this issue as:

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.
