Some widely-used cronie versions still do not have hardening and parse
commands in core dumps.

I didn't seek a CVE for this at the time since it requires a pretty
specific combination of configurations. Namely: setting dumpable=2
without a dump handler, which I couldn't find any distro doing. I have
no objection, of course.
