    1. Topic:

    Updated Ethereal packages that fix various security vulnerabilities are now

    2. Relevant releases/architectures:

    Red Hat Linux 9 - i386

    3. Problem description:

    Ethereal is a program for monitoring network traffic.

    Stefan Esser reported that Ethereal versions 0.10.1 and earlier contain
    stack overflows in the IGRP, PGM, Metflow, ISUP, TCAP, or IGAP dissectors.
     On a system where Ethereal is being run a remote attacker could send
    malicious packets that could cause Ethereal to crash or execute arbitrary
    code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has
    assigned the name CAN-2004-0176 to this issue.

    Jonathan Heussser discovered that a carefully-crafted RADIUS packet could
    cause a crash. The Common Vulnerabilities and Exposures project
    (cve.mitre.org) has assigned the name CAN-2004-0365 to this issue.

    Ethereal 0.8.13 to 0.10.2 allows remote attackers to cause a denial of
    service (crash) via a zero-length Presentation protocol selector. The
    Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
    the name CAN-2004-0367 to this issue.

    Users of Ethereal should upgrade to these updated packages, which contain
    a version of Ethereal that is not vulnerable to these issues.
