ProFTPD < 1.3.5b / 1.3.6x < 1.3.6rc2 weak Diffie-Hellman key

The remote host is using ProFTPD, a free FTP server for Unix and Linux. According to its banner, the version of ProFTPD installed on the remote host is prior to 1.3.5b or 1.3.6x prior to 1.3.6rc2 and is affected by an issue in the modtls module, which might cause a weaker than intended...

DEBIAN-CVE-2018-6829

cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, 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...

CVE-2018-6594

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...

Weak ElGamal Cryptography

Pycryptodome uses weak ElGamal cryptography. Due to an incorrect implementation of ElGamal, the Decisional Diffie-Hellman DDH assumption doesnt hold because of the way the key parameters are generated. This allows attackers who have access to the cipher-text to decrypt the messages and potentiall...

Weak DH Key Exchange Supported (PCI DSS)

At least one of the services on the remote host supports a Diffie-Hellman key exchange using a public modulus smaller than 2048 bits. Diffie-Hellman key exchanges with keys smaller than 2048 bits do not meet the PCI definition of strong cryptography as specified by NIST Special Publication 800-57...

SA159: OpenSSL Vulnerabilities 7-Dec-2017

SUMMARY Symantec Network Protection products using affected versions of OpenSSL are susceptible to two security vulnerabilities. A remote attacker can obtain Diffie-Hellman private key information and sensitive information accidentally transmitted in plaintext over an SSL/TLS connection. AFFECTED...
