Hi, the following vulnerability was published for python-crypto. CVE-2018-6594[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
