All,
Please excuse any ignorance in this e-mail as I am not a RH/CentOS/Fedora user
and may
blunder my way through the correct terminology for my request.
I'm tasked with reconstructing the CentOS version of the GlibC library for
testing with
gethostbyname(). My mission is to show that we are not affected by the latest
exploit for
the product we are shipping targeted for RHEL and CentOS. To do so, I want to
equip
gethostbyname() with additional code.
My objective is to rebuild from source the EXACT version of GlibC for CentOS
6.6.
Afterwards, I will make my changes in the code, rebuild and complete my testing.

But, when looking through the source code for this version on the CentOS
servers I only see:
<http://vault.centos.org/6.6/updates/Source/SPackages/>
[ ] glibc-2.12-1.149.el6_6.4.src.rpm 07-Jan-2015 22:45 15M
[ ] glibc-2.12-1.149.el6_6.5.src.rpm 27-Jan-2015 23:13 15M
Please point me to the correct source tarball, and all required patches so that
I can
reconstruct my loaded version of GlibC. A yum command is also acceptable.
Thanks,
Andy
