Security Bulletin
Summary
Security vulnerabilities have been discovered in OpenSSL.
Vulnerability Details
CVE-ID: CVE-2014-0160
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 Temporal Score: See http://xforce.iss.net/xforce/xfdb/92322
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
Warning: We strongly encourage you to take action as soon as possible as potential implications to your environment may be more serious than indicated by the CVSS score.
CVE-ID: CVE-2014-0076
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by an implementation error in ECDSA (Elliptic Curve Digital Signature Algorithm). An attacker could exploit this vulnerability using the FLUSH+RELOAD cache side-channel attack to recover ECDSA nonces. This vulnerability can only be exploited locally, authentication is not required and the exploit is not complex. An exploit can only partially affect confidentially, but not integrity or availability.
CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91990
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N)
Affected Products and Versions
DS8870 Release 7.2
Remediation/Fixes
IBM strongly suggests that you install the vulnerability fix identified immediately below
| Product | VRMF | APAR | Remediation/First Fix |
| DS8870 | ICS_CVE_2014-0160_v1.0 | N/A | 04/28/2014 |
Please contact your IBM representative to order and install the ICS CD.
After applying the fix, additional instructions are needed for CVE-2014-0160
1) SSL Certificates
- The installation regenerates the SSL certificates and no customer actions are required.
- Users of network facing applications protected by a vulnerable version of OpenSSL should be forced to reset their passwords and should revoke any authentication or session related cookies set prior to the time OpenSSL was upgraded and force the user to re-authenticate.
Workarounds and Mitigations
The following steps can help mitigate, but not eliminate the risks of this vulnerability:
Ensure that the DS8000 HMC is installed behind a firewall that limits access to the ports.
Customers that do not require the CIM interface should stop the CIM Agent.
To stop the CIM Agent using the Web User Interface on the Hardware Master Console (HMC).
