K15479471: Mozilla NSS vulnerability CVE-2016-2834

Security Advisory
 
Original Publication Date: Sep 02, 2016
Updated Date: Dec 27, 2017

Security Advisory Description

Mozilla Network Security Services (NSS) before 3.23, as used in Mozilla Firefox
before 47.0, allows remote attackers to cause a denial of service (memory
corruption and application crash) or possibly have unspecified other impact via
unknown vectors. (CVE-2016-2834)

Impact

BIG-IP

Remote attackers may be able to impact processes. Though Network Security
Services (NSS) is not used by the Traffic Management Microkernel (TMM) or other
data-plane components, it is available in the base system and is used by SNMP
and sflow. In addition, NSS is available to other control-plane components,
such as monitors and utilities available through the Advanced Shell (bash).

iWorkflow, BIG-IQ, and Enterprise Manager

These systems are not vulnerable in a default configuration because they do not
link with the standard NSS libraries. However, base system components may be
impacted, though the attack vectors are unknown.

Security Advisory Status

F5 Product Development has assigned ID 606710 (BIG-IP), ID 606595 (BIG-IQ and
iWorkflow), and ID 606597 (Enterprise Manager) to this vulnerability.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems
