Subject:	Minor problem passing a malformed IP to ping
Date:	Sat, 9 Jul 2005 14:43:13 +0100

I've noticed that calling ping with specially crafted IP addresses  
tends to lead to problems:

ping 192.168.000<...more zeros here...>000.1

With increasing '0' characters, random ascii characters begin to get  
included in the output.
After about 8k of zeros, I get segmentation faults (WinXPh).

Probably a case of GIGO, but reporting it just in case it is  
important security-wise. I'm not clued in on these things.

Best regards,
Denis
