Affected Products and Versions

OpenSSH for GPFS V3.5 for Windows

Remediation/Fixes

In GPFS V3.5.0.21 dated November 2014, IBM upgraded OpenSSH for GPFS on Windows to use OpenSSL 1.0.1j to address this vulnerability. System administrators should update their systems to GPFS V3.5.0.21 by following the steps below.

1. Download the GPFS 3.5.0.21 update package dated November 2014 into any directory on your system. From IBM at http://www-933.ibm.com/support/fixcentral/swg/selectFixes?parent=Cluster%2Bsoftware&product=ibm/power/IBM+General+Parallel+File+System&release=3.5.0&platform=Windows&function=all

2. Extract the contents of the ZIP archive so that the .msi file it includes is directly accessible to your system.

3. Follow the instructions in the README included in the update package in order to install the OpenSSH msi package. This updated OpenSSH msi package is built using OpenSSL 1.0.1j.

If GPFS multiclustering is configured on Windows nodes, upgrade all OpenSSL packages that may have been installed. The following can be done on a small group of nodes at each time (ensuring that quorum is maintained) to maintain file system availability:

a. Stop GPFS on the node
b. Install the version of OpenSSL
c. Restart GPFS on the node

IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3.
