Debian Security Advisory DSA-209-1                   security@debian.org

Package        : wget
Problem type   : directory traversal
                 buffer overflow
Debian-specific: no
CVEs           : CAN-2002-1344

Two problems have been found in the wget package as distributed in
Debian GNU/Linux:

* 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.

Both problems have been fixed in version 1.5.3-3.1 for Debian GNU/Linux
2.2/potato and version 1.8.1-6.1 for Debian GNU/Linux 3.0/woody.

- ------------------------------------------------------------------------

Obtaining updates:

  By hand:
    wget URL
        will fetch the file for you.
    dpkg -i FILENAME.deb
        will install the fetched file.

  With apt:
    deb http://security.debian.org/ stable/updates main
        added to /etc/apt/sources.list will provide security updates

Additional information can be found on the Debian security webpages
at http://www.debian.org/security/

Package        : lynx, lynx-ssl
Problem type   : CRLF injection
Debian-specific: no

lynx (a text-only web browser) did not properly check for illegal
characters in all places, including processing of command line options,
which could be used to insert extra HTTP headers in a request.

For Debian GNU/Linux 2.2/potato this has been fixed in version 2.8.3-1.1
of the lynx package and version 2.8.3.1-1.1 of the lynx-ssl package.

For Debian GNU/Linux 3.0/woody this has been fixed in version 2.8.4.1b-3.2
of the lynx package and version 1:2.8.4.1b-3.1 of the lynx-ssl package.
