  "statement" : "This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3 as it did not include support for SCTP. This was addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2010-0958.html and https://rhn.redhat.com/errata/RHSA-2010-0842.html. Future updates in Red Hat Enterprise Linux 4 and 5 may address this flaw.",
