-Subject: [PATCH] Fix use-after-free bug in __dns_lookup
-
-If the type of the first answer does not match with the requested type,
-then the dotted name was freed. If there are no further answers in
-the DNS reply, this pointer was used later on in the same function.
-Additionally it is passed to the caller, and caused strange
-behaviour.
