                   Fedora Legacy Update Advisory

    Synopsis: Updated tcpdump resolves security vulnerabilities
    Advisory ID: FLSA:1468
    Issue date: 2004-09-29
    Product: Red Hat Linux
    Keywords: Security
    Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=1468
    CVE Names: CAN-2004-0183, CAN-2004-0184

    1. Topic:

    Updated tcpdump packages that fix multiple security vulnerabilities
    are now available.

    2. Relevant releases/architectures:

    Red Hat Linux 7.3 - i386
    Red Hat Linux 9 - i386

    3. Problem description:

    Tcpdump is a command-line tool for monitoring network traffic.

    Tcpdump v3.8.1 and earlier versions contained multiple flaws in the
    packet display functions for the ISAKMP protocol. Upon receiving
    specially crafted ISAKMP packets, tcpdump would try to read beyond
    the end of the packet capture buffer and subsequently crash.

    All users are advised to upgrade to these updated packages, which contain a
    backported fix and are not vulnerable to this issue.

    4. Solution:

    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.

    To update all RPMs for your particular architecture, run:

    rpm -Fvh [filenames]

    where [filenames] is a list of the RPMs you wish to upgrade. Only those
    RPMs which are currently installed will be updated. Those RPMs which are
    not installed but included in the list will not be updated. Note that you
    can also use wildcards (*.rpm) if your current directory *only* contains
    the desired RPMs.

    Please note that this update is also available via yum and apt. Many
    people find this an easier way to apply updates. To use yum issue:

    yum update

    or to use apt:

    apt-get update; apt-get upgrade

    This will start an interactive process that will result in the appropriate
    RPMs being upgraded on your system. This assumes that you have yum or
    apt-get configured for obtaining Fedora Legacy content. Please visit
    http://www.fedoralegacy.org/docs/ for directions on how to configure yum
    and apt-get.

    These packages are GPG signed by Fedora Legacy for security. Our key is
    available from http://www.fedoralegacy org/about/security.php

    You can verify each package with the following command:

        rpm --checksig -v <filename>

    If you only wish to verify that each package has not been corrupted or
    tampered with, examine only the sha1sum with the following command:

        sha1sum <filename>
