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#1451421)

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

 

https://access.redhat.com/articles/11258

 

After installing this update, applications using NSS (for example, Firefox)

must be restarted for this update to take effect.
