Package        : exim exim-tls
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2003-0743

A buffer overflow exists in exim, which is the standard mail transport
agent in Debian.  By supplying a specially crafted HELO or EHLO
command, an attacker could cause a constant string to be written past
the end of a buffer allocated on the heap.  This vulnerability is not
believed at this time to be exploitable to execute arbitrary code.

For the stable distribution (woody) this problem has been fixed in
exim version 3.35-1woody1 and exim-tls version 3.35-3woody1.

For the unstable distribution (sid) this problem has been fixed in
exim version 3.36-8.  The unstable distribution does not contain an
exim-tls package.

We recommend that you update your exim or exim-tls 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.
