Comment: This bulletin contains two (2) F5 Networks security advisories.
         
         There is no impact in the default configuration. This vulnerability is
         exposed only if specific customized command line utilities are in use 
         and specifically configured to use functions in a way that matches the 
         vulnerability.

sol40524634: OpenSSL vulnerability CVE-2016-0797

Security Advisory

Original Publication Date: 03/25/2016

Vulnerability Description

Multiple integer overflows in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 
1.0.2g allow remote attackers to cause a denial of service (heap memory 
corruption or NULL pointer dereference) or possibly have unspecified other 
impact via a long digit string that is mishandled by the (1) BN_dec2bn or (2)
BN_hex2bn function, related to crypto/bn/bn.h and crypto/bn/bn_print.c. 
(CVE-2016-0797)

Impact

ARX, FirePass, LineRate, F5 WebSafe, and Traffix

There is no impact. These F5 products are not affected by this vulnerability.

BIG-IP, BIG-IQ, and Enterprise Manager

There is no impact in the default configuration. This vulnerability is exposed
only if customized iRulesLX, iAppsLX applications, ECV monitors, or OpenSSL 
command line utilities are in use and specifically configured to use the 
BN_dec2bn or BN_hex2bn functions in a way that matches the vulnerability.

Security Issue Status

F5 Product Development has assigned ID 579085 and ID 579098 (BIG-IP), ID 
579385 (BIG-IQ), and ID 579393 (Enterprise Manager) 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.

sol22334603: OpenSSL vulnerability CVE-2016-0799

Security Advisory

Original Publication Date: 03/25/2016

Vulnerability Description

The fmtstr function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and
1.0.2 before 1.0.2g improperly calculates string lengths, which allows remote
attackers to cause a denial of service (overflow and out-of-bounds read) 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-2016-2842. 
(CVE-2016-0799)

Impact

ARX, FirePass, LineRate, F5 WebSafe, and Traffix

There is no impact. These F5 products are not affected by this vulnerability.

BIG-IP, BIG-IQ, and Enterprise Manager

There is no impact in the default configuration. This vulnerability is only 
exposed if customized ECV monitors or OpenSSL command line utilities are in 
use and specifically configured to use the fmtstr function in a way in which 
matches the vulnerability.

Security Issue Status

F5 Product Development has assigned ID 580313 (BIG-IP), ID 580516 (BIG-IQ), 
and ID 580518 (Enterprise Manager) to this vulnerability, and has evaluated

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
