    Synopsis
    ========

    Ethereal is vulnerable to numerous vulnerabilities potentially
    resulting in the execution of arbitrary code or abnormal termination.

    Background
    ==========

    Ethereal is a feature-rich network protocol analyzer.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-analyzer/ethereal < 0.10.12 >= 0.10.12

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

    There are numerous vulnerabilities in versions of Ethereal prior to
    0.10.12, including:

    * The SMB dissector could overflow a buffer or exhaust memory
      (CAN-2005-2365).

    * iDEFENSE discovered that several dissectors are vulnerable to
      format string overflows (CAN-2005-2367).

    * Additionally multiple potential crashes in many dissectors have
      been fixed, see References for further details.

    Impact
    ======

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

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Ethereal users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.12"
