Security Bulletin: SAN Volume Controller and Storwize Family systems are affected by vulnerabilities in OpenSSL (CVE-2014-0160 and CVE-2014-0076)

Vulnerability Details

Security vulnerabilities have been discovered in OpenSSL.

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

After applying the fix, additional instructions are needed for CVE-2014-0160

1) Replace your SSL Certificates

Regenerate the system's private key and SSL certificate by issuing the command line interface (CLI) command "svctask chsystem -regensslcert".

2) Reset User Credentials

Change all user passwords using either the graphical user interface (GUI) or by issuing the CLI command "svctask chcurrentuser -password". No action is necessary for session-related cookies.

Warning: Your environment may require additional fixes for other products, including non-Lenovo products. Please replace the SSL certificates and reset the user credentials after applying the necessary fixes to your environment.

Ensure that all users who have network access to the system are authenticated by a security system such as a firewall.
