Bodhi update submission link:
I have created this epel tracker, but I'm not sure how actively epel version is maintained. Version shipped currently is 1.25, not sure if update is planned.
Previous security issues found in the chrony epel package were fixed by backporting. In this case I'm not sure. The control protocol in 1.25 is not compatible with 1.27 and later, so backporting the new padding requirement would create a completely new protocol incompatible with anything else.
Updating to 1.29.1 seems like a better option to me.
I'm working on update to 1.30.
chrony-1.30-1.el5 has been submitted as an update for Fedora EPEL 5.
chrony-1.30-1.el6 has been submitted as an update for Fedora EPEL 6.
