RHEL 6 : nss (RHSA-2010:0862)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated nss packages that fix one security issue are now available for
Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
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 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.
