Security Bulletin: IBM DS8870 Release 7.2 is affected by an
additional vulnerability in OpenSSL (CVE-2014-0160)
13 June 2014
AusCERT Security Bulletin Summary
Product: IBM DS8870
Operating System: Network Appliance
Impact/Access: Access Privileged Data -- Remote/Unauthenticated
CVE Names: CVE-2014-0160
- --------------------------BEGIN INCLUDED TEXT--------------------
Security Bulletin: IBM DS8870 Release 7.2 is affected by an additional
vulnerability in OpenSSL (CVE-2014-0160)
More support for:
Security vulnerabilities have been discovered in OpenSSL which have an impact
on the IBM Power Servers incorporated in the IBM DS8870. While another IBM
security bulletin addresses this vulnerability in these IBM Power servers
this bulletin addresses this vulnerability in the specific context of these
servers' use in the DS8870. (This bulletin addresses a vulnerability that is
separate and distinct from the DS8870 OpenSSL vulnerability security bulletin
published at https://www-304.ibm.com/support/docview.wss?uid=ssg1S1004582.)
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the TLS/DTLS heartbeat functionality. An
attacker could exploit this vulnerability to expose 64k of private memory
and retrieve secret keys. An attacker can repeatedly expose additional
64k chunks of memory. This vulnerability can be remotely exploited,
authentication is not required and the exploit is not complex. It can be
exploited on any system (ie. server, client, agent) receiving connections
using the vulnerable OpenSSL library.
CVSS Base Score: 5

CVSS Environmental Score*: Undefined??
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
IBM's standard and recommended configuration for the IBM DS8870 does not
connect the service processor ports on the IBM Power servers to any network
other than a private network to the DS8870 hardware management console
(HMC). As a result, the OpenSSL vulnerability in the DS8870's Power servers
should generally be a limited threat if you have not connected the Power
Server service processor ports in your DS8870 to other networks and follow
the mitigations identified below.
Affected Products and Versions
DS8870 Release 7.2
This vulnerability is fixed in DS8870 Release 7.3. Please contact your
IBM representative to order and install DS8870 Release 7.3.
IBM currently plans to make a fix available for this vulnerability in
DS8870 Release 7.2 in a service release scheduled for late June. This
bulletin will be updated when this is available.
Although IBM suggests you install a fix for this vulnerability, you can
consider the mitigations identified below in determining when and how to
implement these fixes in your particular environment.
Workarounds and Mitigations
The following steps can help mitigate, but not eliminate the risks of this
vulnerability: Ensure that the DS8870 HMC is installed behind a firewall
that limits access to the HMC ports.
Ensure that access to the DS8870 HMC is only by trusted personnel.
Ensure that no Flexible Service Processor (FSP) ports on the Power servers
in the DS8870 are connected to a reachable network (this is the standard
and recommended DS8870 configuration).
