next in thread | raw e-mail | index | archive | help
When program uses strtok() and call gethostbyname/addr after it, strtok() memory becomes corrupted, because private function init_services() from gethostnamaddr.c module uses strtok() too! AND ONLY ONE STRTOK PARSER MAY BE ACTIVE AT ONCE. Now init_services() strtok() corrupts program strtok() internal variables. Garrett, please, get rid of strtok() in init_services()! Currently this bug strongly affects at least tcp_wrapper. -- Andrey A.
