Security Bulletin: IBM SDN for Virtual Environments is affected by a vulnerability in OpenSSL (CVE-2014-0160)
A security vulnerability has been discovered in OpenSSL.
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.
Affected Products and Versions
IBM SDN VE, Unified Controller, VMware Edition: 1.0.0

IBM SDN VE, Dove Management Console, VMware Edition: 1.0.0
IBM recommends updating affected IBM SDN VE, Unified Controllers to the latest versions of IBM SDN VE for which IBM is providing a fix, which are identified below:
IBM SDN VE, Unified Controller, VMware Edition: version 1.0.1 or later
IBM SDN VE, Unified Controller, KVM Edition: version 1.0.1 or later
IBM SDN VE, Unified Controller, OpenFlow Edition: version 1.0.1 or later
These versions are available via Passport Advantage.
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.
