Fedora 27: python-crypto Security Update
Summary
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
