CVE-2010-2253

lwp-download in libwww-perl before 5.835 does not reject downloads to
filenames that begin with a . (dot) character, which allows remote servers
to create or overwrite files via (1) a 3xx redirect to a URL with a crafted
filename or (2) a Content-Disposition header that suggests a crafted
filename, and possibly execute arbitrary code as a consequence of writing
to a dotfile in a home directory.
