Personally, I would do one of three things:
1. Use the -m command to run 'yum install <version>' which /might/ work.
2. Uninstall the newer package and install the version you want. (Check the
'state' directive to do this.)
3. Pin that package version when creating the server/VM so as not to be
updated.
#3 is useful to us as we kickstart all our servers and VMs, and this
eliminates the problem going forward. Then, when we're ready to upgrade
the pinned package, we have an ansible playbook that unpins that version,
installs the new version (even if not latest), then re-pins.
HTH.

The present version of ansible can't handle downgrades with the yum module
There's been a few discussions of this over time but this is the most
recent I think, and it looks like it might get fixed on 2.4 perhaps

If you want to do a specific version you are better off not using the yum
module at present but rather shell/command to do so instead.
