Massive SNMP vulnerability reports

[Hal Pomeranz]

Many of you have already seen this, but I think it needs the widest
dissemination possible.

CERT Advisory 2002-03 (http://www.cert.org/advisories/CA-2002-03.html)
describes a suite of buffer overflow and denial-of-service attacks
against the SNMP implementations used by essentially every vendor of
network-capable devices.  Disable SNMP, block the SNMP ports at your
firewall (most critical are 161 and 162, tcp and udp-- the CERT
Advisory lists other less commonly used ports), and obtain patches
from your vendor.  

Do it now.
