Email from OVH about security alert

I received an email from OVH asking me to install "A new version of the RTM component (RTMv2)" because the old version has a security problem. The recommended way to do this is to run this command

wget -qO - https://last-public-ovh-infra-yak.snap.mirrors.ovh.net/yak/archives/apply.sh | OVH_PUPPET_MANIFEST=distribyak/catalog/master/puppet/manifests/common/rtmv2.pp bash

The instructions warn that this may not work and sure enough, it does not work

Download: [yak/archives/catalog_puppet_bin_fedora21_amd64.tar.gz?1566933254]

curl: (22) The requested URL returned error: 404 Not Found
gzip: stdin: unexpected end of file
tar: Child returned status 1
tar: Error is not recoverable: exiting now

If this does not work then I am supposed to follow instructions for doing it manually. There are instructions for Debian/Ubuntu, Centos, and FreeBSD. However my server has Fedora 21.

So my question is, how to install this security update?
