dns_ai_nextaf NULL pointer dereference #15

Closed wahern closed 8 years ago

wahern commented 8 years ago

Previously dns_ai_nextent worked for numeric addresses even if no resolver object was provided. Now the first thing that dns_ai_nextent calls is dns_ai_nextaf, which immediately tries to dereference a ai->res to reach ai->res->resconf.
