Note that for RHEL5 this fix probably also need to be applied to ia32entry-xen.S
created by linux-2.6-xen.patch

Working exploit has been made public.
Comment 25 Mark J. Cox (Product Security) 2007-09-27 11:22:18 EDT
Jan, updated kernels are progressing through quality engineering.  We'll be
releasing them (for RHEL3,4,5) the moment they pass!
Comment 28 Jan Iven 2007-09-28 10:19:05 EDT
While the Errata kernels have been announced on the enterprise-watch list 18h
ago and are available via RHN, it appears as if the SRPMs aren't yet on
ftp.redhat.com. Could somebody please look for them?



Comment 30 Mark J. Cox (Product Security) 2007-10-01 02:14:51 EDT
Jan, we had a short outage on our main ftp server on Friday during which time
the SRPMS we pushed on Thursday were missing from the ftp site.  (They were at
all times available via Red Hat Network).  

I checked this yesterday and the RHEL3 and RHEL4 srpms were present, but the
RHEL5 ones were missing.  This was escalated to our production engineering team
who resolved it.

I've checked again today and the kernel SRPMS for RHEL3, RHEL4, RHEL5 are all
there now (note RHEL5 updates are always in a different place at
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Client/en/os/SRPMS )
