    Synopsis
    ========

    A bug in Zebedee allows a remote attacker to perform a Denial of
    Service attack.

    Background
    ==========

    Zebedee is an application that establishes an encrypted, compressed
    tunnel for TCP/IP or UDP data transfer between two systems.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-misc/zebedee < 2.5.3 *>= 2.4.1-r1
    >= 2.5.3

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

    "Shiraishi.M" reported that Zebedee crashes when "0" is received as the
    port number in the protocol option header.

    Impact
    ======

    By performing malformed requests a remote attacker could cause Zebedee
    to crash.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Zebedee users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose net-misc/zebedee
