DSA 124-1-mtr

by Nikola Strahija on March 26th, 2002 The authors of mtr released a new upstream version, noting a non-exploitable buffer overflow in their ChangeLog. Przemyslaw Frasunek, however, found an easy way to exploit this bug, which allows an attacker to gain access to the raw socket, which makes IP spoofing and other malicious network activity possible.

The problem has been fixed by the Debian maintainer in version 0.41-6
for the stable distribution of Debian by backporting the upstream fix
and in version 0.48-1 for the testing/unstable distribution.

We recommend that you upgrade your mtr 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.
