Red Hat Security Advisory
Synopsis: Important: nss security update
Advisory ID: RHSA-2012:0532-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0532.html
Issue date: 2012-04-30
=====================================================================
1. Summary:
Updated nss packages that fix one security issue are now available for Red
Hat Enterprise Linux 5.6 Extended Update Support
The Red Hat Security Response Team has rated this update as having
important security impact.
2. Relevant releases/architectures:
Red Hat Enterprise Linux EUS (v. 5.6 server) - i386, ia64, ppc, s390x, x86_64
3. Description:
Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications.
It was found that a Certificate Authority (CA) issued fraudulent HTTPS
certificates. 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. (BZ#734316)
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.
All NSS users should upgrade to these updated packages, which correct this
issue. After installing the update, applications using NSS must be
restarted for the changes to take effect.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
5. Bugs fixed (http://bugzilla.redhat.com/):
734316 - Fraudulent certificates signed by DigiNotar CA certificate (MFSA 2011-34)
