Fedora 26: Security Update for python-crypto Addresses ElGamal Threat

PyCrypto is a collection of both secure hash functions (such as MD5 and

SHA), and various encryption algorithms (AES, DES, RSA, ElGamal, etc.).

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/pycrypto/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
