-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 will be freed. If there are no further answers in
-the DNS reply, this pointer will be used later on in the same function.
-Additionally it is passed to the caller, and may cause strange behaviour.
-
-For example, the following busybox commands are triggering a segmentation
-fault with uClibc 0.9.30.x
-
-  - nslookup ipv6.google.com
-  - ping ipv6.google.com
-  - wget http//ipv6.google.com/
