-----BEGIN PGP SIGNED MESSAGE-----

Hello,

The CERT/CC has recently seen discussions in a public forum detailing
potential vulnerabilities in several TCP/IP implementations (Linux,
OpenBSD, and FreeBSD). We are particularly concerned about these types
of vulnerabilities because they have the potential to be exploited
even if the target machine has no open ports.

The messages can be found here:

http://lists.netsys.com/pipermail/full-disclosure/2002-September/001668.html
http://lists.netsys.com/pipermail/full-disclosure/2002-September/001664.html
http://lists.netsys.com/pipermail/full-disclosure/2002-September/001643.html

Note that one individual claims two exploits exist in the
underground. At this point in time, we do not have any more
information, nor have we been able to confirm the existence of these
vulnerabilities.

We would appreciate any feedback or insight you may have. We will
continue to keep an eye out for further discussions regarding this
topic.

FYI,
Ian
