SOL15159: OpenSSL vulnerability CVE-2014-0160
Security AdvisorySecurity Advisory
Original Publication Date: 04/08/2014
Description
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not
properly handle Heartbeat Extension packets, which allows remote attackers to
obtain sensitive information from process memory via crafted packets that
trigger a buffer over-read, as demonstrated by reading private keys, related
to d1_both.c and t1_lib.c, aka the Heartbleed bug.(CVE-2014-0160)
Impact
Systems that are vulnerable can be exploited to retrieve information from
memory. That information may include the private keys used for TLS/DTLS.
- - Virtual servers using an SSL profile configured with the default Native SSL
ciphers are not vulnerable. Only virtual servers using an SSL profile
configured to use ciphers from the Compat SSL stack are vulnerable. In
addition, back-end resources are not protected by virtual servers that do not
use SSL profiles and pass SSL traffic directly through to the back-end web
servers.
- - The Configuration utility on the management interface is vulnerable.
- - Clients using the BIG-IP Edge client for Android are not vulnerable to this
vulnerability. However, clients using the BIG-IP Edge client for Windows, Mac
OS, or Linux are vulnerable if they are used to connect to a compromised
FirePass or BIG-IP APM system.
Status
F5 Product Development has assigned ID 456033 (BIG-IP) to this vulnerability.

Recommended action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the table does not list any version in the column, then no
upgrade candidate currently exists.
To mitigate this vulnerability, you should consider the following
recommendations:
- - Limit the Configuration utility access to a trusted management network.
- - Use only Native SSL stack ciphers. Do not use ciphers from the Compat SSL
stack. For information about the Native and Compat ciphers, refer to SOL13163:
SSL ciphers supported on BIG-IP platforms (11.x).
- - Back-end resources are not protected by virtual servers that do not use SSL
profiles and pass SSL traffic through to the back-end web servers. When
possible, you should protect back-end resources by using SSL profiles to
terminate SSL at the BIG-IP.
