[CentOS] gnutls bug

I am running centos6.4.   Where do I find the updated gnutls packages?    I
see the updated source file here:
http://vault.centos.org/6.5/updates/Source/SPackages/

But I don't see the correct version of the packages in the 6.4 tree here:
http://vault.centos.org/6.4/updates/x86_64/Packages/

Where should I be looking for the updated package for 6.4?

Thanks.
