Re: Denial of Service Attacks INFO

UDP Bomb - By sending a UDP packet with incorrect information in the
header, some Sun-OS 4.1.3 Unix boxes will panic and then reboot.

Anyone willing to say _what_ this magic incorrect information is?  I'd
much rather not have to take the time to grab the patch, uncompile both
it and the file(s) it replaces, and try to figure it out from there.

From that snippet you quoted I'd guess thats its the SunOS flaw where if
it gets a packet with ip_options of an invalid size, it freaks out.  I
guess I should quit doing all this important stuff and go read that file.
