SOL75152412: OpenSSL vulnerability CVE-2016-2108
Security Advisory
Original Publication Date: 05/19/2016
Vulnerability 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 Issue Status
F5 Product Development has assigned IDs 591042, 591325, 591327, 591328, and
591329 (BIG-IP), ID 594024 (BIG-IQ), ID 594030 (Enterprise Manager), ID 500324
(ARX), and ID LRS-60730 (LineRate) to this vulnerability, and has evaluated
the currently supported releases for potential vulnerability.

Vulnerability 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.
F5 responds to vulnerabilities in accordance with the Severity values
published in the previous table. The Severity values and other security
vulnerability parameters are defined in SOL4602: Overview of the F5 security
vulnerability response policy.
BIG-IP, BIG-IQ, 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.
