How to fix?

Upgrade to version 2.6.1 or greater.

Overview

pycrypto is a Cryptographic module for Python.

Affected versions of this package are vulnerable Information Exposure. The Crypto.Random.atfork function in PyCrypto before 2.6.1 does not properly reseed the pseudo-random number generator (PRNG) before allowing a child process to access it, which makes it easier for context-dependent attackers to obtain sensitive information by leveraging a race condition in which a child process is created and accesses the PRNG within the same rate-limit period as another process.
