Package        : eterm
Vulnerability  : buffer overflow
Problem-Type   : local
Bugtraq ID     : 7708

"bazarr" discovered that eterm is vulnerable to a buffer overflow of
the ETERMPATH environment variable.  This bug can be exploited to gain
the privileges of the group "utmp" on a system where eterm is
installed.

For the stable distribution (woody), this problem has been fixed in
version 0.9.2-0pre2002042903.1.

The old stable distribution (potato) is not affected by this bug.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you update your eterm package.

Upgrade Instructions
--------------------

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.
