Statement
The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and 5 did not
include L2TP functionality, and therefore are not affected by this
issue. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat
Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0007.html and https://rhn.redhat.com/errata/RHSA-2011-0330.html.
