Description


Updated nss packages that fix one security issue are now available for Red
Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate 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 TLS 1.2 could use the MD5 hash function for
signing ServerKeyExchange and Client Authentication packets during a TLS
handshake. A man-in-the-middle attacker able to force a TLS connection to
use the MD5 hash function could use this flaw to conduct collision attacks
to impersonate a TLS server or an authenticated TLS client. (CVE-2015-7575)

All nss users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. For the update to take
effect, all services linked to the NSS library must be restarted, or the
system rebooted.
