# The advisory scopes the flaw to the Standard client component, which IBM ships with the main
# product media as well as standalone (installable-component-names page). Every install in the
# affected window carries the C client library, so no component filtering is applied and the
# version window alone decides.
#
# Only the 9.4.5 CD releases are affected and IBM names no fix within that branch - the
# remediation is an upgrade to 10.0.0.0.
