sol52349521: OpenSSL vulnerability CVE-2016-2842
Security Advisory
Original Publication Date: 04/27/2016
Vulnerability Description
The doapr_outch function in crypto/bio/b_print.c in OpenSSL 1.0.1 before
1.0.1s and 1.0.2 before 1.0.2g does not verify that a certain memory
allocation succeeds, which allows remote attackers to cause a denial of
service (out-of-bounds write or memory consumption) or possibly have
unspecified other impact via a long string, as demonstrated by a large amount
of ASN.1 data, a different vulnerability than CVE-2016-0799. (CVE-2016-2842)
Impact
ARX, FirePass, and F5 WebSafe
There is no impact; these F5 products are not affected by this vulnerability.
BIG-IP, BIG-IQ, Enterprise Manager, LineRate, and Traffix SDC
In default configurations, there is no impact. This vulnerability exposure is
limited to the OpenSSL utility, as well as BIG-IP Extended Content
Verification (ECV) monitors that are customized by the OpenSSL utility to
parse ASN.1 data. Standard BIG-IP monitors, such as HTTPS monitors, are not
affected by this vulnerability.
Security Issue Status
F5 Product Development has assigned ID 580340 (BIG-IP), ID 580541 (BIG-IQ), ID
580544 (Enterprise Manager), LRS-60657 (LineRate), and INSTALLER-2274 (Traffix
SDC) to this vulnerability, and has evaluated the currently supported releases
for potential vulnerability.
To determine if your release is known to be vulnerable, the components or
features that are affected by the vulnerability, and for information about

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, Enterprise Manager, LineRate, and Traffix SDC
To mitigate this vulnerability, you should ensure that any custom BIG-IP ECV monitor or custom configurations that rely on OpenSSL utilities (which depend on the function specified in this vulnerability) are only interacting with trusted systems in your environment.
