SCO Security Advisory
Subject: Linux: wget directory traversal and buffer overrun vulnerabilities
Advisory number: CSSA-2003-003.0
Issue date: 2003 January 16
Cross reference:
______________________________________________________________________________
1. Problem Description
Stefano Zacchiroli found a buffer overrun in the url_filename
function, which would make wget segfault on very long urls.
Steven M. Christey discovered that wget did not verify the FTP
server response to a NLST command: it must not contain any
directory information, since that can be used to make a FTP
client overwrite arbitrary files.
2. Vulnerable Supported Versions
System Package
----------------------------------------------------------------------
OpenLinux 3.1.1 Server prior to wget-1.7.1-3.i386.rpm
OpenLinux 3.1.1 Workstation prior to wget-1.7.1-3.i386.rpm
OpenLinux 3.1 Server prior to wget-1.7.1-3.i386.rpm
OpenLinux 3.1 Workstation prior to wget-1.7.1-3.i386.rpm
3. Solution
The proper solution is to install the latest packages. Many
customers find it easier to use the Caldera System Updater, called
cupdate (or kcupdate under the KDE environment), to update these
packages rather than downloading and installing them by hand.
