"Updated nss packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.2, 6.3, and 6.4 Extended Update Support.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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

A flaw was found in the way NSS handled invalid handshake packets. A
remote attacker could use this flaw to cause a TLS/SSL client using
NSS to crash or, possibly, execute arbitrary code with the privileges
of the user running the application. (CVE-2013-5605)

All NSS users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing this
update, applications using NSS must be restarted for the changes to
take effect."
