    1. Topic:

    Updated Ethereal packages available to fix a number of remotely
    exploitable 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
    Red Hat Linux 9 - i386

    3. Problem description:

    Ethereal is a program for monitoring network traffic.

    A number of security issues affect Ethereal. By exploiting these issues it
    may be possible to make Ethereal crash or run arbitrary code by injecting a
    purposefully malformed packet onto the wire or by convincing someone to
    read a malformed packet trace file.

    Multiple off-by-one vulnerabilities exist in Ethereal 0.9.11 and earlier in
    the AIM, GIOP Gryphon, OSPF, PPTP, Quake, Quake2, Quake3, Rsync, SMB, SMPP,
    and TSP dissectors. They do not properly use the tvb_get_nstringz and
    tvb_get_nstringz0 functions. Common Vulnerabilities and Exposures project
    (cve.mitre.org) has assigned the name CAN-2003-0356 to these issues.

    Multiple integer overflow vulnerabilities exist in Ethereal 0.9.11 and
    earlier in the Mount and PPP dissectors. (CAN-2003-0357)

    A vulnerability in the DCERPC dissector exists in Ethereal 0.9.12 and
    earlier, allowing remote attackers to cause a denial of service (memory
    consumption) via a certain NDR string. (CAN-2003-0428)

    The OSI dissector in Ethereal 0.9.12 and earlier causes by invalid IPv4 or
    IPv6 prefix lengths, possibly triggering a buffer overflow. (CAN-2003-0429)

    The SPNEGO dissector in Ethereal 0.9.12 and earlier allows remote attackers
    to cause a denial of service (crash) via an invalid ASN.1 value.
    (CAN-2003-0430)

    The tvb_get_nstringz0 function in Ethereal 0.9.12 and earlier does not
    properly handle a zero-length buffer size. (CAN-2003-0431)

    Ethereal 0.9.12 and earlier does not handle certain strings properly in the
    BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, ISIS, and RMI dissectors.
    (CAN-2003-0432)

    Users of Ethereal should update to the erratum packages containing Ethereal
    version 0.9.13, which are not vulnerable to these issues.

    4. Solution:

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

    Please note that this update is available via Red Hat Network. To use Red
    Hat Network, launch the Red Hat Update Agent with the following command:

    up2date

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

    5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
