[BlueOnyx:16040] Patched bash for RH 4.9

[George F. Nemeyer]

I expect Oracle has a boatload of legacy machines that they still need to
support, so it appears they're still creating at least some updates for
RHEL 4.9.

There's newly patched bash versions for 4.9 here:

 http://public-yum.oracle.com/repo/EnterpriseLinux/EL4/latest/i386/

There are now 3 successively new patched versions, the lastest being dated
today:

   bash-3.0-27.0.3.el4.i386.rpm   26-Sep-2014 15:42  1.7 M

and source:

   bash-3.0-27.0.3.el4.src.rpm    26-Sep-2014 15:42  4.3 M

There's been some 'work arounds' found to the earlier patches, so it may
take several more patch revisions before the holes are completely closed.
For those really worried about this, it's worth checking your repositories
often for a while until it all settles out.

There's also some later versions of other programs in the repository
above, so it may be worth seeing if any of those are useful for legacy
boxes.

For any who may have any RAQ 4 boxes (AMD K6-III CPUs which are i586), the
compiled Oracle bash rpm *seems* to work ok.  However, the running bash
reports i686 despite the repo saying .i386.  So use caution before blindly
updating packages.

For those K-6 machines, it may be better to grab source packages and
compile them for the i586 since there are a few machine instructions in
the 686 that aren't present in the 586 architecture.  If the 586
encounters instructions it dosen't know about, the application will crash
with an 'illegal instruction' fault.
