in short, -runas is supposed to reduce privileges to a
bare minimum (after all initialization is completed),
but the process still has all the supplementary groups
which should be dropped too.

Can a CVE id be assigned for this issue?

Sorry, we were contacted directly to provide a CVE name, and I'm not
sure if that was before or after you wrote this mail (probably after).
That bug has been updated with the assigned CVE name, CVE-2011-2527.

Thanks, sorry for missing this.
