Package        : nvi, nvi-m17n
Vulnerability  : Format string vulnerability
Problem-Type   : local privileges
Debian-specific: no

Takeshi Uno found a very stupid format string vulnerability in all
versions of nvi (in both, the plain and the multilingualized version).
When a filename is saved, it ought to get displayed on the screen.
The routine handling this didn't escape format strings.

This problem has been fixed in version 1.79-16a.1 for nvi and
1.79+19991117-2.3 for nvi-m17n for the stable Debian GNU/Linux 2.2.

Even if we don't believe that this could lead into somebody gaining
access of another users account if he hasn't lost his brain, we
recommend that you upgrade your nvi packages.

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.
