Description Florian Weimer 2023-02-23 15:17:49 UTC 
The sgetsgent function checks errno for ERANGE, but sgetsgent_r only returns ERANGE, but does not set errno to ERANGE. As a result, sgetsgent does not detect failure at all, and returns indicating success without filling in the struct sgrp result.

Upstream patch under review:
