We may get more than one response before exiting out of loop in grub_net_dns_lookup, but buffer was allocated for the first response only, so storing answers from subsequent replies wrote past allocated size. We never really use more than the very first address during lookup so there is little point in collecting all of them. Just quit early if we already have some reply. Code needs serious redesign to actually collect multiple answers and select the best fit according to requested type (IPv4 or IPv6). Reported and tested by Michael Chang <mchang@suse.com>
