I just verified that sudo fix seems good within yakkety. Marking it as verification-done.

When that happens, sudo crashes when attempting to look up the group name for the debug log. Upstream has commited a simple fix for this issue, it has been commited to Yakkety, and uploaded to Xenial. [Test Case] I currently don't know an easy way to reproduce this, it is environment-specific. A package containing the fix was successfully tested in the problematic environment. [Regression Potential] A regression in the patch would prevent users from using sudo. The risk of regression is low since the patch only changes the debug log. Original report: If the user is in a group with no name (because libnss-db got removed and the group was defined there, for example...) then: the call to sudo_debug_printf in sudo_getgrgid (plugins/sudoers/pwutil.c, line 462) causes a SEGV when trying to get item->d.gr->gr_name (since item->d.gr is NULL).
