Comment 1 RHEL Program Management 2011-01-11 20:07:15 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

Comment 2 RHEL Program Management 2011-01-12 15:24:04 UTC
This request was erroneously denied for the current release of
Red Hat Enterprise Linux.  The error has been fixed and this
request has been re-proposed for the current release.

Comment 3 Jan Lieskovsky 2011-03-01 17:06:49 UTC
https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2010-4262 is the primary

with  this security flaw. Closing this one.
