Well, I am not spreading rumour....
http://www.securiteam.com/securitynews/Smurf_attack_exhausts_Cabletron_Enter
asys__SSR_CPU.html
I am the one who reported this to CERT and Securiteam.com. During May last
year, we experienced smurf (just smurf with TTL=0) and this exhausted all of
our SSR CPU time... So you can see the consequence. After the event, we
replaced *ALL* the SSRs with Foundrys.
Cabletron Systems knows this (see this
http://www.enterasys.com/support/techbltn/tb1057-9.html). They can't solve
the problem 7 months after the event. The release note is not telling the
whole story. When I was on the venue, I can't telnet, all OSPF routes were
dropped, 100% CPU utilization, and no packet can get thru'. NO ACL can solve
this problem, no rate-shaping command effective.... All the packet travels
to L3 and then dropped by kernel and trigger 100% CPU usage.... it is a
nightmare.... (and I am still so scared..)
So, DO NOT USE CABLETRON. This is what I can tell.
