   OS	Do this...
   CentOS 6+ Fedora 22+ Red Hat 10+	sudo yum -y update glibc glibc-common glibc-devel glibc-headers glibc-static glibc-utils nscd
   Ubuntu 12.04+	sudo apt-get update && sudo apt-get install --only-upgrade libc6
   CentOS 5	Nothing - this OS is not affected
   Other OSes	See Unsupported operating systems (GLIBC DNS vulnerability)

Your version of glibc should now be updated.
