use after free in handle close
libcurl contains a heap use after free flaw in code related to closing an easy handle. When closing and cleaning up an "easy" handle in the `Curl_close()` function, the library code first frees a struct (without clearing the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
