Quick fix

PYSEC-2013-29 — pycrypto: upgrade to the fixed version with the command below.

pip install --upgrade 'pycrypto>=19dcf7b15d61b7dc1a125a367151de40df6ef175'

Details

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.
