This was a problem fixed in glibc 2.18, so that version, as shipped in
F20, and 2.20, as we have in F21, are not vulnerable. If you are
running F19 or earlier, you should update.

If you're running (a supported version of) a different Linux
distribution with an old version, patches are likely available.
