PACKAGE : wget
SUMMARY : Directory transversal vulnerability
DATE : 2002-12-13 18:23:00
ID : CLA-2002:552

RELEASES : 6.0, 7.0, 8

DESCRIPTION
GNU wget is a freely available network utility to retrieve files
using HTTP and FTP.
Steven M. Christey reported[1] a vulnerability[2] in some ftp
clients, including wget up to version 1.8.2 (inclusive).
The vulnerability resides in the way wget handles server answers to
LIST and multiple GET requests. If the filenames in the answer begin
with characters pointing to parent directories (like "../" or "/"),
wget can download files to that location, thus overwritting arbitrary
files.
The version 1.8.2 distributed together with this advisory fixes that
vulnerability and some other minor bugs besides adding some new
features[3].
SOLUTION
All wget users are advised to upgrade.
