Ian, So right now this is a scary rumor floating around the security scene? Is there any particular trace, or any further details your aware of? Also, I think it may be safe to assume the Mac OS X/Jaguar may be vulnerable as well. AFAIK it runs of the BSD IP Stack, so it's more than likely that it is vulnerable if this exploit is in fact a reality. I'll keep an eye out for any suspicious traffic myself, as I'm sure will the rest of the list. Thanks for the warning, as if this is real, it could be be potentially very harmful. Any great C Coders out there start pouring over the code yet? Derek

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/001667.html 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
