A vulnerability has been found and corrected in wget:

GNU Wget 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 (CVE-2010-2252).

Packages for 2008.0 and 2009.0 are provided as of the Extended
Maintenance Program. Please visit this link to learn more:
