Package        : masqmail
Vulnerability  : buffer overflows
Problem-Type   : local
Debian-specific: no
CVE Id         : CAN-2002-1279

A set of buffer overflows have been discovered in masqmail, a mail
transport agent for hosts without permanent internet connection.  In
addition to this privileges were dropped only after reading a user
supplied configuration file.  Together this could be exploited to gain
unauthorized root access to the machine on which masqmail is
installed.

These problems have been fixed in version 0.1.16-2.1 for the current
stable distribution (woody) and in version 0.2.15-1 for the unstable
distribution (sid).  The old stable distribution (potato) is not
affected since it doesn't contain a masqmail package.

We recommend that you upgrade your masqmail package immediately.

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.
