     [ Advisory for Electrocomm ]

    ElectroComm allows you to connect to a comm port on
    a computer over a network using any Telnet client.
    The program can fall victim to a denial of service.

    /-|=[who is vulnerable]=|-\
    Electrocomm 2.0 has been tested to be vulnerable.
    Prior versions are assumed to be vulnerable as well.

    /-|=[testing it]=|-\
    Sending two bursts of characters with a length of
    about 160000 each to port 23 will peg CPU to 100%
    and then crash with:
    Run-time error '381':
    Invalid array index.

    I have made a perl script that exploits this. It is
    in the advisory that is available on the DHC site.

    None known at the moment.
