We should be checking for the ownership of the file for which flags are being set, rather than just for write access.

Statement:

Red Hat is aware of this issue and is tracking it via the following bug:
https://bugzilla.redhat.com/CVE-2010-1641.

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 GFS2 file system.

A future kernel update in Red Hat Enterprise Linux 5 will address this issue.
