3. 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)
