https://github.com/shadow-maint/shadow/pull/97 is my proposed patch. It currently only deals with the immediate security issue of allowing users that don't have % echo "$(whoami):$(id -g):1" >> /etc/setgid ... set up. I've tested this with a couple of different setups and it appears to preserve

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 s

I had a preliminary patch written, but it was getting quite complicated (shadow's codebase is much more complicated than I expected -- and the /etc/subgid parsing code is intertwined with the parsing code for all of the other /etc/... files). I am working on it though. I've also email the SUSE Sec

Serge: I will submit a patch later today. However, I just thought that it's probably better that "allow_setgroups" should be "ignore_setgroups" and we retain the current behaviour (we don't write anything to /proc/$pid/setgroups) -- which allows a user (or runtime) to explicitly disable setgroups e
