[tkined] Possible bug in scotty ICMP support

Dear All,

I wrote a scotty script that monitors devices using the icmp scotty command. It
worked, but after a modify it started to crash, while running the "icmp echo",
with signal 11 Segmentation fault.

I have analyzed the source code and have discovered a possible bug.

The possible bug is referred the scotty version 2.1.9, but I verified is
present in the version 2.1.10.

The line 115 of the file scotty-2.1.9/tnm/generic/tnmIcmp.c:

icmpPtr->targets = (TnmIcmpTarget *) icmpPtr + sizeof(TnmIcmpRequest);

should be changed as:

icmpPtr->targets =
        (TnmIcmpTarget *) ((char *) icmpPtr + sizeof(TnmIcmpRequest));

Any comment will be welcome!

Thanks

Dario Palmisano
