Remediation
Red Hat statement
This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not have support for the XFS file system. It did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 5 as it did not backport the upstream commit ef14f0c1 that introduced the vulnerability. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2012-0350.html, and https://rhn.redhat.com/errata/RHSA-2012-0333.html.
