    Synopsis
    ========

    Mulitple overflows and vulnerabilities exist in Ethereal which may
    allow an attacker to crash the program or run arbitrary code.

    Background
    ==========

    Quote from http://www.ethereal.com

    "Ethereal is used by network professionals around the world for
    troubleshooting, analysis, software and protocol development, and
    education. It has all of the standard features you would expect in a
    protocol analyzer, and several features not seen in any other product.
    Its open source license allows talented experts in the networking
    community to add enhancements. It runs on all popular computing
    platforms, including Unix, Linux, and Windows."

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
         net-analyzer/ethereal <= 0.10.2 >= 0.10.3

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

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

    * Thirteen buffer overflows in the following protocol dissectors:
      NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and TCAP.

    * A zero-length Presentation protocol selector could make Ethereal
      crash.

    * A vulnerability in the RADIUS packet dissector which may crash
      ethereal.

    * A corrupt color filter file could cause a segmentation fault.

    Impact
    ======

    These vulnerabilities may cause Ethereal to crash or may allow an
    attacker to run arbitrary code on the user's computer.

    Workaround
    ==========

    While a workaround is not currently known for this issue, all users are
    advised to upgrade to the latest version of the affected package.

    Resolution
    ==========

    All users should upgrade to the current version of the affected
    package:

        # emerge sync

        # emerge -pv ">=net-analyzer/ethereal-0.10.3"
        # emerge ">=net-analyzer/ethereal-0.10.3"
