    ('binary' encoding is not supported, stored as-is) Vulnerable systems: unpatched "standalone Flash
    players" (Macromedia Shockwave Flash player
    versions before January 2002?)

    Fix: "In response to the discovery of the virus, in
    January Macromedia released an update to its
    standalone Flash player that causes the player to
    ignore the "exec" action."

    Exploit Description: "Vengy's demo showed how
    the "save" command could be used to create a batch
    program on the hard disk of Flash standalone player
    users who viewed a movie containing the Trojan
    horse code. In the demo, the Trojan program
    executed when the victim rebooted his or her
    computer."

    "Vengy's advisory on the Flash "save" vulnerability is
    at http://www.geocities.com/cyber_flash5/ ."

    "Macromedia's technical note on the "exec" hole is at
    http://www.macromedia.com/support/flash/ts/docume
    nts/standalone_update.htm ."

    "A description of the SWF/LFM-926 virus is at
    http://www.sophos.com/virusinfo/analyses/swflfm926.
    html "

    I also tracked down this:
    http://www.macromedia.com/support/flash/ts/docume
    nts/swf_clear.htm

    The SWF/LFM-926 virus exploites a related
    ActionScript command known as fscommand:exec
    which is in another vulnerability.

    These seem to be different than bid 2162.

    This is my first post to bugtraq and I am mearly trying
    relaying information from another source in order that
    vulnerabilities get the attention they deserve.
