-Subject: [PATCH] forward.c: fix CVE-2017-13704
-
-Fix SIGSEGV in rfc1035.c answer_request() line 1228 where memset()
-is called with header & limit pointing at the same address and thus
-tries to clear memory from before the buffer begins.
-
-answer_request() is called with an invalid edns packet size provided by
-the client.  Ensure the udp_size provided by the client is bounded by
-512 and configured maximum as per RFC 6891 6.2.3 "Values lower than 512
-MUST be treated as equal to 512"
-
-The client that exposed the problem provided a payload udp size of 0.
