Package        : gftp
Vulnerability  : Information Retrieval
Problem-Type   : local unauthorized Information Retrieval
Debian-specific: no

Stephane Gaudreault told us that version 2.0.6a of gftp displays the
password in plain text on the screen within the log window when it is
logging into an ftp server.  A malicious collegue who is watching the
screen could gain access to the users shell on the remote machine.

This problem has been fixed by the Security Team in version 2.0.6a-3.2
for the stable Debian GNU/Linux 2.2.

We recommend that you upgrade your gftp package.

wget url
	will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
