Amazon Linux AMI : openssl (ALAS-2014-273)

This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

A flaw was found in the way OpenSSL determined which hashing algorithm
to use when TLS protocol version 1.2 was enabled. This could possibly
cause OpenSSL to use an incorrect hashing algorithm, leading to a
crash of an application using the library. (CVE-2013-6449)

It was discovered that the Datagram Transport Layer Security (DTLS)
protocol implementation in OpenSSL did not properly maintain
encryption and digest contexts during renegotiation. A lost or
discarded renegotiation handshake packet could cause a DTLS client or
server using OpenSSL to crash. (CVE-2013-6450)

A NULL pointer dereference flaw was found in the way OpenSSL handled
TLS/SSL protocol handshake packets. A specially crafted handshake
packet could cause a TLS/SSL client using OpenSSL to crash.
