Not sure about Centos, can't find anything. Looks like someone has submitted a patch for Fedora - https://bodhi.fedoraproject.org/updates/FEDORA-2016-0f9e9a34...

I'm guessing Ubuntu will add something here once they get a fixed released - http://www.ubuntu.com/usn/

Should be able to see centos updates here, once they are released, for files glibc-2.12* with a 2016 timestamp -
