Amazon Linux AMI : nss HTTPS Certificate Weakness (ALAS-2011-21)

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


Synopsis :

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

Description :

Network Security Services (NSS) is a set of libraries designed to
support the development of security-enabled client and server
applications.

It was found that the Malaysia-based Digicert Sdn. Bhd. subordinate
Certificate Authority (CA) issued HTTPS certificates with weak keys.
This update renders any HTTPS certificates signed by that CA as
untrusted. This covers all uses of the certificates, including SSL,
S/MIME, and code signing. Note: Digicert Sdn. Bhd. is not the same
company as found at digicert.com. (BZ#751366)

Note: This fix only applies to applications using the NSS Builtin
Object Token. It does not render the certificates untrusted for
applications that use the NSS library, but do not use the NSS Builtin
Object Token.
