Affected Products and Versions

IBM PureApplication System V2.0 (GPFS Pattern type 1.2.0) using IBM GPFS V3.5.0.19

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, V4.1.0.7 or V3.5.0.19.

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 3.5.0.28

http://www-933.ibm.com/support/fixcentral/swg/downloadFixes?parent=PureSystems&product=ibm/WebSphere/PureApplication+System&release=2.0.0.1&platform=All&function=fixId&fixids=update-gpfs-3.5.0.28&includeRequisites=0&includeSupersedes=0&downloadMethod=http

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
these CVEs.

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