    Synopsis
    ========

    Multiple vulnerabilities exist in Ethereal, which may allow an attacker
    to run arbitrary code or crash the program.

    Background
    ==========

    Ethereal is a feature rich network protocol analyzer.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-analyzer/ethereal < 0.10.10 >= 0.10.10

    Description
    ===========

    There are multiple vulnerabilities in versions of Ethereal earlier than
    0.10.10, including:

    * The Etheric and 3GPP2 A11 dissectors are vulnerable to buffer
      overflows (CAN-2005-0704 and CAN-2005-0699).

    * The GPRS-LLC could crash when the "ignore cipher bit" option is
      enabled (CAN-2005-0705).

    * Various vulnerabilities in the IAPP, JXTA, and sFlow dissectors.

    Impact
    ======

    An attacker might be able to use these vulnerabilities to crash
    Ethereal and execute arbitrary code with the permissions of the user
    running Ethereal, which could be the root user.

    Workaround
    ==========

    For a temporary workaround you can disable all affected protocol
    dissectors. However, it is strongly recommended that you upgrade to the
    latest stable version.

    Resolution
    ==========

    All Ethereal users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.10"
