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

medium Nessus Plugin ID 70905

Language:

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.

Solution

Run 'yum update python-crypto' to update your system.
