This is a good time to remind everyone that CentOS 6.7 isn't the same
as RHEL 6.7. When you pay Red Hat, they'll provide security patches
when you stay with non-tip point releases. CentOS only provides
packages for the tip, so, if you aren't on the tip (6 tip is currently
6.8), you're missing security fixes for a lot more things than just
Dirty COW.

Yeah, I used to be one of the vendors, and I was sad that we never got
close to providing good support for CentOS tip. I'm not surprised
that it's still a problem 9 years later.
