wget -- multiple HTTP client download filename vulnerability

GNU Wget version 1.12 and earlier uses a server-provided filename
instead of the original URL to determine the destination filename of
a download, which allows remote servers to create or overwrite
arbitrary files via a 3xx redirect to a URL with a .wgetrc filename
followed by a 3xx redirect to a URL with a crafted filename, and
possibly execute arbitrary code as a consequence of writing to a
dotfile in a home directory.
