RHSA-2017:1364 - Important: nss security and bug fix update

Synopsis

Important: nss security and bug fix update

Type/Severity

Security Advisory Important

Topic

An update for nss is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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

Security Fix(es):

  • A null pointer dereference flaw was found in the way NSS handled empty SSLv2 messages. An attacker could use this flaw to crash a server application compiled against the NSS library. (CVE-2017-7502)

Bug Fix(es):

  • The Network Security Services (NSS) code and Certificate Authority (CA) list have been updated to meet the recommendations as published with the latest Mozilla Firefox Extended Support Release (ESR). The updated CA list improves compatibility with the certificates that are used in the Internet Public Key Infrastructure (PKI). To avoid certificate validation refusals, Red Hat recommends installing the updated CA list on June 12, 2017. (BZ#1448488)

Solution

After installing this update, applications using NSS (for example, Firefox) must be restarted for this update to take effect.
