3. Description:

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

A flaw was found in the way NSS matched SSL certificates when the
certificates had a Common Name containing a wildcard and a partial IP
address. NSS incorrectly accepted connections to IP addresses that fell
within the SSL certificate's wildcard range as valid SSL connections,
possibly allowing an attacker to conduct a man-in-the-middle attack.
(CVE-2010-3170)

All NSS users should upgrade to these updated packages, which provide NSS
version 3.12.8 to resolve 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

5. Bugs fixed (http://bugzilla.redhat.com/):

630047 - CVE-2010-3170 firefox/nss: doesn't handle IP-based wildcards in X509 certificates safely
