Fedora Update Notification
2018-03-06 17:26:39.511249

Name : python-crypto
Product : Fedora 26
Version : 2.6.1
Release : 22.fc26
URL : http://www.pycrypto.org/
Summary : Cryptography library for Python
Description :
PyCrypto is a collection of both secure hash functions (such as MD5 and
SHA), and various encryption algorithms (AES, DES, RSA, ElGamal, etc.).

Update Information:

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 a fix for
this problem backported from pycryptodome.

[ 1 ] Bug #1542313 - CVE-2018-6594 python-crypto: Weak ElGamal key parameters
in PublicKey/ElGamal.py allow attackers to obtain sensitive information by reading ciphertext

This update can be installed with the "dnf" update program. Use
su -c 'dnf upgrade python-crypto' at the command line.
For more information, refer to the dnf documentation available at
