Package        : tkmail
Vulnerability  : insecure temporary files
Problem-Type   : local
Debian-specific: no

It has been discovered that tkmail creates temporary files insecurely.
Exploiting this an attacker with local access can easily create and
overwrite files as another user.

This problem has been fixed in version 4.0beta9-8.1 for the current
stable distribution (woody), in version 4.0beta9-4.1 for the old
stable distribution (potato) and in version 4.0beta9-9 for the
unstable distribution (sid).

We recommend that you upgrade your tkmail 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.
