nspr, nss security update

CentOS Errata and Security Advisory CESA-2013:0213

Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications. Netscape Portable Runtime (NSPR) provides platform
independence for non-GUI operating system facilities.

It was found that a Certificate Authority (CA) mis-issued two intermediate
certificates to customers. These certificates could be used to launch
man-in-the-middle attacks. This update renders those certificates as
untrusted. This covers all uses of the certificates, including SSL, S/MIME,
and code signing. (BZ#890605)

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.

In addition, the nss package has been upgraded to upstream version 3.13.6,
the nss-util package has been upgraded to upstream version 3.13.6, and the
nspr package has been upgraded to upstream version 4.9.2. These updates
provide a number of bug fixes and enhancements over the previous versions.
(BZ#891663, BZ#891670, BZ#891661)

Users of NSS, NSPR, and nss-util are advised to upgrade to these updated
packages, which fix these issues and add these enhancements. After
installing this update, applications using NSS, NSPR, or nss-util must be
restarted for this update to take effect.
