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. This vulnerability can be remotely exploited,
authentication is not required and the exploit is not complex. An exploit can
only partially affect the confidentially, but not integrity or availability.
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)

After applying the fix, additional instructions are needed for CVE-2014-0160
1) Replace your SSL Certificates.
You need to revoke existing SSL certificates and reissue new certificates.
To install a new self-signed certificate, use the task HMC Management > Manage
Certificates. Click Create > New Certificate, select Self-signed and then
click OK. Fill in the requested information and click OK. Reply Yes to the
prompt to replace the certificate and restart the HMC. Click Ok to restart.
To install a new certificate signed by a Certificate Authority first generate
a new certificate signing request, sign the request, then import the
certificate.
For further information on managing HMC certificates see:
http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=%2Fp7ha1%2Fmanagecertificates.htm
2) Reset User Credentials
Users of network facing applications protected by a vulnerable version of
OpenSSL should be forced to reset their passwords and force the user to
re-authenticate.
This includes:
- - all HMC user accounts configured for local authentication as well as those
configured for kerberos and LDAP authentication.
- - Flexible Service Processor (FSP) user accounts for all managed servers.
- - Any operating system user id or application password on a partition managed
by the HMC when the partition is enabled for HMC remote virtual terminal
(vterm) or remote 5250 console.
For further information on managing HMC users and passwords see
http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/topic/p7ha1/hmchmcmanagement-administration.htm
Warning: Your environment may require additional fixes for other products,
including non-IBM products. Please replace the SSL certificates and reset the
user credentials after applying the necessary fixes to your environment.
