I've just sent a request for a CVE. I'm working on the patch now. My current plan is that allow_setgroups will be the default for all mappings that are present in /etc/subgid -- but any "implicit" mappings (like mapping your own group) will be deny_setgroups by default (because that's the biggest security issue coming out of this bug -- that *any* user can drop groups, not just the ones with subgids set up).
