Affected Products and Versions

IBM PureApplication System V2.1 (GPFS Pattern type 1.2.1.0) using IBM GPFS V4.1.0.5
IBM PureApplication System V2.1.0.1 (GPFS Pattern type 1.2.2.0) using IBM GPFS V4.1.0.7
IBM PureApplication System V2.1.1 (GPFS Pattern type 1.2.3.0) using IBM GPFS V4.1.0.7

Remediation/Fixes

GPFS server or client instances deployed with the affected GPFS Pattern versions are vulnerable. To determine whether deployed GPFS sever or client instances are affected by these GPFS security vulnerabilities, run the Get Cluster Status operation ( for a GPFS server instance ) or the GPFS Client Status operation ( for a GPFS client instance ) to verify the version reported for the GPFS nodes. The instance is affected if the GPFS version is V4.1.0.5 or V4.1.0.7.

The solution is to apply one of the following interim fixes or upgrade the PureApplication System to V2.1.2 or higher, and upgrade this instance using the pattern upgrade procedure.

GPFS 4.1.1.2
http://www-933.ibm.com/support/fixcentral/swg/downloadFixes?parent=PureSystems&product=ibm/WebSphere/PureApplication+System&release=2.1.1.0&platform=Linux&function=fixId&fixids=update-gpfs-4.1.1.2&includeRequisites=0&includeSupersedes=0&downloadMethod=http

The GPFS Pattern type 1.2.4.0 that is delivered with IBM PureApplication System V2.1.2.0 installs GPFS 4.1.1.2. Any instances deployed with this GPFS pattern type version or upgraded to this version will not be affected by this CVE.

Whenever possible, the PureApplication System upgrade option is recommended instead of the interim fixes.
