If anyone has any objections, please let me know. ------------------ From: =?UTF-8?q?Manuel=20Sch=C3=B6lling?= <manuel.schoelling@xxxxxx> commit 84a7c0b1db1c17d5ded8d3800228a608e1070b40 upstream. dns_query() credulously assumes that keys are null-terminated and returns a copy of a memory block that is off by one.
