CVE-2018-6594 (GCVE-0-2018-6594)

Vulnerability from cvelistv5 – Published: 2018-02-03 03:00 – Updated: 2024-08-05 06:10
VLAI?
Summary
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.
Severity ?
No CVSS data available.
