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.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/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 https://exchange.xforce.ibmcloud.com/vulnerabilities/91990
CVSS Environmental Score*: Undefined

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. You need to be sure not to generate the new certificates using the old private key and create a new private key (ie using "openssl genrsa") and use that new private key to create the new certificate signing request (CSR).
2. Reset User Credentials
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.
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.
For the IBM Power Hardware Management Console (HMC)
1. Replace the SSL certificates on both HMCs.
- To install a new self-signed certificate:
- To install a new certificate signed by a Certificate Authority:
a. Click HMC Management > Manage Certificates.
b. Click Create > New Certificate, select Self-signed and click OK.
c. Enter the required information and click OK.
d. When you are prompted to replace the certificate and restart the HMC, click Yes > OK.
a. Generate a new certificate signing request.
b. Sign the request.
c. Import the certificate.
- 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.
a. For the hscroot user, use the following miauth command to change the password on both HMCs:
- miauth -pw -p hmc -u hscroot
