Problem Description:

A vulnerability in all versions of wget prior to and including 1.8.2
was discovered by Steven M. Christey. The bug permits a malicious
FTP server to create or overwriet files anywhere on the local file
system by sending filenames beginning with "/" or containing "/../".
This can be used to make vulnerable FTP clients write files that can
later be used for attack against the client machine.
