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.
