>From the reports is seem to be the older revisions of IOS (10.X and 11.0)
in certain hardware configurations and the Cisco 700 Series ISDN access
routers (not running IOS) are vulnerable.
We keep getting conflicting reports for FreeBSD and OpenBSD. The are
enough reports and indications that those operating systems are indeed
vulnerable but the vulnerabilitiy may not show up in all configurations
depending on the enviroment, the intensity of cosmic rays, the phase of
the moon, and if the testing person is left or right handed.
An external "land" attack should not be an issue if you are filtering IP
address spoofing at your ingress routers. You _ARE_ doing so? Correct?
Well in case you forgot you can find Paul Ferguson's "Network Ingress
Filtering: Defeating Denial of Service Address Spoofing" Internet Draft at
ftp://ietf.org/internet-drafts/draft-ferguson-ingress-filtering-03.txt
I highly recommend you implement it's recommendations. Of curse you are
still at the mercy of those behind the filter.
