* 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)
* 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

recommends installing the updated CA list on June 12, 2017. (BZ#1451421)
