Conectiva Linux Advisory: wget

Dec 16, 2002, 18:57 (0 Talkback[s])

- --------------------------------------------------------------------------
CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

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