Medium Nessus Plugin ID 100536


The remote Scientific Linux host is missing one or more security updates.


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.
