Comment 11 Eugene Teo (Security Response) 2010-08-18 03:42:29 UTC 
Statement:

This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include
support for the Ext4 filesystem. A future kernel update in Red Hat Enterprise
Linux 5 will address this issue.
Comment 12 errata-xmlrpc 2010-09-29 14:53:55 UTC 
This issue has been addressed in following products:

  Red Hat Enterprise Linux 5
