"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,
consider installing the updated CA list on June 12,
2017."
