Subject: Linux kernel 2.2.x vulnerability/exploit

I'm sorry if this has been noticed before, but since I did't find anything
in the archives, I post it here.
There seems to be a bug in kernels 2.2.x (tested on 2.2.7 and 2.2.9), that
causes them to panic when they are sent a large number of specific ICMP
packages. I think the problem comes from the combination of the mangled
header length (shorter or longer ihl's don't cause hangup) and the random
ICMP packets (random type/subtype and source address) this program sends.
Windows 9x and FreeBSD 3.0 seem to be unaffected.

[exploit snipped for brevity]
