Remediation/Fixes
GPFS server or client instances deployed with the affected GPFS Pattern
versions are vulnerable. To determine whether deployed GPFS server 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 solution is to apply one of the following interim fixes:
