    Synopsis: Updated Ethereal packages are available
    Advisory ID: RHSA-2002:290-07
    Issue date: 2003-01-09
    Updated on: 2003-01-08
    Product: Red Hat Linux
    Keywords: ethereal dissector PPP LMP TDS BGP
    Cross references:
    Obsoletes: RHSA-2002:169
    CVE Names: CAN-2002-1355 CAN-2002-1356

    1. Topic:

    Updated Ethereal packages are available which fix various security issues.

    2. Relevant releases/architectures:

    Red Hat Linux 7.2 - i386, ia64
    Red Hat Linux 7.3 - i386
    Red Hat Linux 8.0 - i386

    3. Problem description:

    Ethereal is a package designed for monitoring network traffic on your
    system. Several security issues have been found in the Ethereal packages
    distributed with Red Hat Linux versions 7.2, 7.3, and 8.0

    Multiple integer signedness errors in the BGP dissector in Ethereal
    0.9.7 and earlier allow remote attackers to cause a denial of service
    (infinite loop) via malformed messages. This problem was discovered by
    Silvio Cesare. CAN-2002-1355

    Ethereal 0.9.7 and earlier allows remote attackers to cause a denial
    of service (crash) and possibly execute arbitrary code via malformed
    packets to the LMP, PPP, or TDS dissectors. CAN-2002-1356

    Users of Ethereal should update to the erratum packages containing Ethereal
    version 0.9.8 which is not vulnerable to these issues.

    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 Red Hat Network. Many
    people find this an easier way to apply updates. To use Red Hat Network,
    launch the Red Hat Update Agent with the following command:


    This will start an interactive process that will result in the appropriate
    RPMs being upgraded on your system.

    5. RPMs required:

    Red Hat Linux 7.2:




    Red Hat Linux 7.3:



    Red Hat Linux 8.0:
