[CentOS] CVE-2015-0235 - glibc gethostbyname

Hi,

For reasons which are too tiresome to bore you all with, I have an 
obligation to look after a suite of legacy CentOS 4.x systems which 
cannot be migrated upwards.

I note on https://access.redhat.com/articles/1332213 the following 
comment from a RHN person:

>post an update for it as soon as it's ready. Thank you for your 
>patience!

Is there *any* prospect of updated glibc packages for CentOS 4.x 
being made available?

Cheers
S.
