Fedora 27 : python-crypto (2018-913c225b49)

The textbook ElGamal implementation is not secure. PyCrypto and some other implementations use the wrong algorithm, which may lead to some information disclosure simply by looking at the encrypted text. For a full description, see https://github.com/dlitz/pycrypto/issues/253 This update includes ...

[SECURITY] [DLA 1283-1] python-crypto security update

Package : python-crypto Version : 2.6-4+deb7u8 CVE ID : CVE-2018-6594 Debian Bug : 889999 python-crypto generated weak ElGamal key parameters, which allowed attackers to obtain sensitive information by reading ciphertext data i.e., it did not have semantic security in face of a ciphertext-only...

Debian DLA-1283-2 : python-crypto security update

This is an update to DLA-1283-1. In DLA-1283-1 it is claimed that the issue described in CVE-2018-6594 is fixed. It turns out that the fix is partial and upstream has decided not to fix the issue as it would break compatibility and that ElGamal encryption was not intended to work on its own. The...

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...

Libgcrypt Information Disclosure Vulnerability (CNVD-2018-05552)

Libgcrypt is a cryptographic library developed as an independent module of GnuPG. An information disclosure vulnerability exists in Libgcrypt versions 1.8.2 and earlier. The vulnerability arises because cipher/elgamal.c in Libgcrypt improperly encodes plaintext when used to directly encrypt...

CVE-2018-6829

CVE-2018-6829 affects Libgcrypt’s ElGamal (cipher/elgamal.c) up to version 1.8.2. When used to encrypt messages directly, it can improperly encode plaintexts, allowing a ciphertext-only attacker to recover sensitive information. The issue is tied to Libgcrypt’s DDH assumption not holding for its ...

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...
