    Warning! New Version of the "Klez" I-Worm is Spreading Fast - Klez.h

    Kaspersky Labs announces the exposure of a new modified version of the
    "Klez" Internet-worm - Klez.h, already resulting in numerous computer
    infections in many countries including Japan, China, Austria and the
    Czech Republic.

    To gain entry to a computer the worm exploits a vulnerability in the
    Internet Explorer security system (the IFRAME vulnerability). Due to
    this Klez is able to imperceptibly infect computers immediately after
    the infected message is read. This special feature practically discounts
    the human factor and many times over raises the effectiveness of Klez.h
    to infect and to spread.

    To protect against Klez.h Kaspersky Labs recommends that you immediately
    update the Kaspersky Anti-Virus database. To remove the threat of
    infection from the Klez.h worm and any other modification of this worm,
    you should install the required patch for Internet Explorer. It can be
    found on the Microsoft site at the following address:


    A more detailed explanation about the Klez worm family can be found in
    the Kaspersky Virus Encyclopedia at:

    Funny, the MS site says that the update is included in IE 5.0  SP2, are we to assume it is also included in 5.5 SP2?
    After all, I just went 5.0 to 5.5 last week ;-)

    Never certain, but after a lot of observation on how those bullitins work at MS,  only the versions affected are stated - anything included is specifically stated - so the assumption is anything not specifically stated does not apply.

    Later, Rickster
