Security Advisory
Original Publication Date: May 20, 2016
Updated Date: Sep 07, 2017
Applies to (see versions):
Security Advisory Description
The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c
allows remote attackers to execute arbitrary code or cause a denial of service
(buffer underflow and memory corruption) via an ANY field in crafted
serialized data, aka the "negative zero" issue. (CVE-2016-2108)
Impact
A successful attack can create memory corruption, which may result in
processes restarting or arbitrary code execution.
Security Advisory Status
F5 Product Development has assigned IDs 591042, 591325, 591327, 591328, and
591329 (BIG-IP), ID 594024 (BIG-IQ and iWorkflow), ID 594030 (Enterprise
Manager), ID 500324 (ARX), and LRS-60730 (LineRate) to this vulnerability, and
has evaluated the currently supported releases for potential vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H591062-3 on the Diagnostics >
Identified > High screen.

* BIG-IP products are vulnerable through SSL certification validation when
validating both client certificates (such as an SSL client profile) or server
certificates (such as an SSL forward proxy).
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.
BIG-IP, BIG-IQ, iWorkflow, and Enterprise Manager
To minimize risk, ensure that certificates accepted from clients or servers
are configured to validate against a known-secure Certificate Authority (CA).
ARX
To mitigate this vulnerability, you should permit access to the ARX GUI only
over a secure network.
LineRate
To mitigate this vulnerability, you should avoid configuring certificate
bundles on the SSL profile from an untrusted source.
