Statement:

This issue did not affect the Linux kernels as shipped with Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG as they did not include support for the Hierarchical File System (HFS) file system. This has been addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2012-0007.html.
