DescriptionA potential race condition issue exists within the Amazon EFS mount helper in efs-utils and aws-efs-csi-driver when using TLS to mount file systems. The mount helper allocates a local port for stunnel to receive NFS connections prior to applying the TLS tunnel. In affected versions, concurrent mount operations can allocate the same local port, leading to either failed mount operations or an inappropriate mapping from an EFS customer’s local mount points to that customer’s EFS file systems.A potential race condition issue exists within the Amazon EFS mount helper in efs-utils and aws-efs-csi-driver when using TLS to mount file systems.

Unless explicitly stated as not affected, all previous versions of packages in any minor update stream of a product listed here should be assumed vulnerable, although may not have been subject to full analysis.
