hrm, in reality a bunch of non-router vulnerabilities affect (to some
extent anyway) network operations.

one good thing, practically no sctp deployment... and, hopefully for
networking equipment there's already local firewall/acl capability
That said there are a few 'network devices' which are linux based (not
just Vyatta! :) )
o Cisco Guards
o Arbor Peakflow (at least the X version)
o some-route-optmization systems
o dns/mail/ntp/blah widgets
It's nice to get some notice of this, it's also nice it got fixed in
later kernels (who knows what kernel Peakflow-X has deployed or what
custom mods happen to it?)
Quickly searching <favorite search engine> shows quite a few
SCTP/Linux problems reported over at least the last 2.5 years. The one
mentioned here seems to be: CVE-2009-0065 reported Jan 5th 2009, only
redhat reports back a fix so far (according to mitre).
Putting on my Paul Quinn/Roland Dobbins/Darrel Lewis hat - another
good argument for infrastructure acls!! :)
