When an FTP wildcard LIST operation fails, libcurl omits the restoration path meant for successful listings, leaving the write callback set to the internal listing parser and the write callback data pointing directly to the easy handle. Subsequent reuse of this handle triggers an immediate crash, and cloning it via curl_easy_duphandle() copies this corrupted state into the duplicate. If the original handle is subsequently freed, executing a transfer on the cloned handle causes a heap use-after-free read against the dangling handle reference; alternatively, reusing the original or cloned handle while changing only CURLOPT_WRITEDATA (and omitting CURLOPT_WRITEFUNCTION) results in type confusion, forcing the internal parser to interpret incoming server response bytes into memory at the application-supplied write data pointer.
