`launch_resolve()` leaks `addr` if `DisableNetwork` is set or the nameservers can't be configured. ``` static int launch_resolve(edge_connection_t *exitconn) { char *addr = tor_strdup(exitconn->_base.address); struct evdns_request *req = NULL; tor_addr_t a; int r; int options = get_options()->ServerDNSSearchDomains ? 0 : DNS_QUERY_NO_SEARCH; if (get_options()->DisableNetwork) return -1; /* What? Nameservers not configured? Sounds like a bug. */ if (!nameservers_configured) { log_warn(LD_EXIT, "(Harmless.) Nameservers not configured, but resolve " "launched. Configuring."); if (configure_nameservers(1) < 0) { return -1; } } ```
