      KaZaA Lunches Ads in the Wrong Security Zone
    ------------------------------------------------------------------------

    SUMMARY

    A security vulnerability in the KaZaA causes it to launch its ads in the
    local zone. This would allow a potential attacker to execute scripts
    embedded inside the ads with elevated privileges.

    DETAILS

    Vendor response:
    KaZaA was contacted 6 Jan 03 via their bug report page.

    Workaround:
    To immunize KaZaA from this defect you should remove the permissions from
    the directory it launches ads from. This has a nice side effect of not
    showing ads. The directory to secure is: %WinDir%\AdCache

    Alternatively, KaZaA Lite can be used since it doesn't have ads or spyware
