    Package        : mtr
    Vulnerability  : buffer overflow
    Problem-Type   : remote
    Debian-specific: no
    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.
