Summary

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.
