                   Fedora Legacy Update Advisory

    Synopsis: Updated tcpdump resolves security vulnerability
    Advisory ID: FLSA:1222
    Issue date: 2004-01-31
    Product: Red Hat Linux
    Keywords: Security
    Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=1222
    CVE Names: CAN-2003-0989, CAN-2004-0055, CAN-2004-0057
    - -----------------------------------------------------------------------

    1. Topic:

    Updated tcpdump packages are now available that fix multiple security
    vulnerabilities which may allow remote attackers to exploit these issues
    by sending carefully-crafted packets to a victim. If the victim uses
    tcpdump, these packets could result in a denial of service, or possibly
    execute arbitrary code as the 'pcap' user.

    2. Relevant releases/architectures:

    Red Hat Linux 7.2 - i386
    Red Hat Linux 7.3 - i386
    Red Hat Linux 8.0 - i386

    3. Problem description:

    Tcpdump is a command-line tool for monitoring network traffic. Tcpdump can
    capture and display the packet headers on a particular network interface
    or on all interfaces. Tcpdump can display all of the packet headers, or
    just the ones that match particular criteria.

    George Bakos discovered flaws in the ISAKMP decoding routines of tcpdump
    versions prior to 3.8.1. The Common Vulnerabilities and Exposures project
    (cve.mitre.org) has assigned the name CAN-2003-0989 to this issue.

    Jonathan Heusser discovered an additional flaw in the ISAKMP decoding
    routines for tcpdump 3.8.1 and earlier. The Common Vulnerabilities and
    Exposures project (cve.mitre.org) has assigned the name CAN-2004-0057 to
    this issue.

    Jonathan Heusser discovered a flaw in the print_attr_string function in the
    RADIUS decoding routines for tcpdump 3.8.1 and earlier. The Common
    Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
    name CAN-2004-0055 to this issue.

    Users of tcpdump should update to these update packages, which contain a
    backported security patch that corrects this issue.

    Fedora Legacy would like to thank George Bakos and Jonathan Heusser for
    discovering and disclosing these issues, as well as Christian Pearce for
    providing a backported fix for Red Hat Linux 7.2, 7.3, and 8.0.

    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/download for directions on how to configure
    yum and apt-get.
