Amazon Linux AMI : python-crypto Information Disclosure Vulnerability (ALAS-2013-243)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

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.
