"An update for nss is now available for Red Hat Enterprise Linux 7.

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.

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# 1451421)

security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
