Indeed, you are right.  The problem is that, by default, "guix pull"
downloads the latest source from:

  http://git.savannah.gnu.org/cgit/guix.git/snapshot/master.tar.gz

and unfortunately, something is currently broken on Savannah, and that
snapshot is stuck on the commit before the glibc security update :-(

Until that's fixed, here's a workaround:

--8<---------------cut here---------------start------------->8---
$ git clone --depth 1 git://git.sv.gnu.org/guix.git master
Cloning into 'master'...
[...]
$ rm -rf master/.git
$ tar czf master.tar.gz master --sort=name address@hidden --{owner,group}=root:0
$ guix pull --url=master.tar.gz
--8<---------------cut here---------------end--------------->8---
