    Package : tcpdump
    Vulnerability : infinite loop
    Problem-Type : remote
    Debian-specific: no
    CVE Id : CAN-2003-0093

    A problem has been discovered in tcpdump, a powerful tool for network
    monitoring and data acquisition. An attacker is able to send a
    specially crafted RADIUS network packet which causes tcpdump to enter
    an infinite loop.

    For the stable distribution (woody) this problem has been
    fixed in version 3.6.2-2.4.

    The old stable distribution (potato) does not seem to be affected
    by this problem.

    The unstable distribution (sid) is not affected by this problem anymore.

    We recommend that you upgrade your tcpdump 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.
