------------------------------------------------------------------
A. Background
CERT has issued an advisory:
CERT Advisory CA-2002-03 Multiple Vulnerabilities in Many
Implementations of the Simple Network Management Protocol
(SNMPv1) containing information about the vulnerabilities.
Hewlett-Packard Company will revise this bulletin as new
information becomes available.
---------------------------------------------------------
hp procurve switch 2524
---------------------------------------------------------
hp procurve switch 2525 (product J4813A) is vulnerable to
some issues. Patches in process.
---------------------------------------------------------
NNM (Network Node Manager)
---------------------------------------------------------
Some problems were found in NNM product were related to
trap handling. Patches in process.
---------------------------------------------------------
JetDirect Firmware (older versions only)
---------------------------------------------------------
ONLY some older versions of JetDirect Firmware are
vulnerable to some of the issues. The older firmware
can be upgraded in most cases, see list below.
JetDirect Firmware Version State
========================== =====
X.08.32 and higher NOT Vulnerable
X.21.00 and higher NOT Vulnerable
where X represents an alpha character for your device.
JetDirect Product Numbers that can be freely upgraded
to X.08.32 or X.21.00 or higher firmware.
EIO (Peripherals Laserjet 4000, 5000, 8000, etc...)
J3110A 10T

J3264A 500X Token Ring
J3265A 500X 10/100
----------------------------------------------------------
HP-UX Systems running snmpd or OPENVIEW
----------------------------------------------------------
Any HP-UX 10.X or 11.X system running snmpd or snmpdm is
vulnerable. To determine if your HP-UX system has snmpd
or snmpdm installed:
swlist -l file | grep snmpd
B. Fixing the problem
Install the appropriate patch or firmware revision or work
around problem as detailed below.
C. Recommended solution
---------------------------------------------------------
hp procurve switch 2524
---------------------------------------------------------
No known workaround. Patches are in process.
---------------------------------------------------------
NNM (Network Node Manager)
---------------------------------------------------------
Disable snmpd and snmpdm as detailed for HP-UX below.
Patches are in process.
---------------------------------------------------------
MC/ServiceGuard
---------------------------------------------------------
Concerning the impact of disabling the SNMP agent on nodes
in MC/ServiceGuard or ServiceGuard OPS Edition clusters:
If SNMP is disabled on nodes running in MC/ServiceGuard
or ServiceGuard OPS Edition clusters, it will no longer be
possible for cluster monitoring applications that use the
cluster SNMP MIB to obtain the correct status for the cluster.
Examples of such applications are ClusterView, ClusterView Plus
or EMS High Availability Monitors, which all receive
cluster-related SNMP information from the cluster nodes.
This means that these applications will no longer display the
correct status for the cluster, including the cluster starting
or halting, nodes leaving or joining the cluster, and application
packages starting up or halting in the cluster.
NOTE: All supported versions of MC/ServiceGuard as well as
ServiceGuard OPS Edition are affected by this issue.
The ServiceGuard Manager product does not use the cluster
SNMP MIB, and therefore is _NOT_ affected by the
disabling of SNMP on cluster nodes.
---------------------------------------------------------
Event Monitoring System (EMS)
---------------------------------------------------------
It should also be noted that if an MC/ServiceGuard or ServiceGuard
OPS Edition application package has package resources defined
that use EMS High Availability Monitors, then those package
resources will no longer contain the current status for the
cluster. It may be necessary to remove the definition for these
package resources in order to allow continued operation of the
package after SNMP has been disabled.
---------------------------------------------------------
JetDirect Firmware (older versions only)
---------------------------------------------------------
Update firmware to X.08.32(or higher) or X.21.00(or higher)
as applicable.
----------------------------------------------------------
HP-UX Systems running snmpd or OPENVIEW
----------------------------------------------------------
The following patches are available now:
PHSS_26137 s700_800 HP-UX 10.20 OV EMANATE14.2 Agent$
PHSS_26138 s700_800 HP-UX 11.X OV EMANATE14.2 Agent$
PSOV_03087 Solaris 2.X EMANATE Release 14.2 $
All three patches are available from:
http://support.openview.hp.com/cpe/patches/
In addition PHSS_26137 and PHSS_26138 will soon be available
from:
http://itrc.hp.com
============================================================
NOTE: The patches are labeled OV (Open View). However, the
patches are also applicable to systems that are _NOT_
running Open View.
============================================================
Workaround for HP-UX Systems:
If a patch is not available for your platform or you cannot
install an available patch, snmpd and snmpdm can be disabled
by removing their entries from /etc/services and removing the
execute permissions from /usr/sbin/snmpd and /usr/sbin/snmpdm.

---------------------------------------------------------
MC/ServiceGuard
---------------------------------------------------------
Concerning the impact of disabling the SNMP agent on nodes
in MC/ServiceGuard or ServiceGuard OPS Edition clusters:
If SNMP is disabled on nodes running in MC/ServiceGuard
or ServiceGuard OPS Edition clusters, it will no longer be
possible for cluster monitoring applications that use the
cluster SNMP MIB to obtain the correct status for the cluster.
Examples of such applications are ClusterView, ClusterView Plus
or EMS High Availability Monitors, which all receive
cluster-related SNMP information from the cluster nodes.
This means that these applications will no longer display the
correct status for the cluster, including the cluster starting
or halting, nodes leaving or joining the cluster, and application
packages starting up or halting in the cluster.
NOTE: All supported versions of MC/ServiceGuard as well as
ServiceGuard OPS Edition are affected by this issue.
The ServiceGuard Manager product does not use the cluster
SNMP MIB, and therefore is _NOT_ affected by the
disabling of SNMP on cluster nodes.
---------------------------------------------------------
Event Monitoring System (EMS)
---------------------------------------------------------
It should also be noted that if an MC/ServiceGuard or ServiceGuard
OPS Edition application package has package resources defined
that use EMS High Availability Monitors, then those package
resources will no longer contain the current status for the
cluster. It may be necessary to remove the definition for these
package resources in order to allow continued operation of the
package after SNMP has been disabled.
---------------------------------------------------------
JetDirect Firmware (older versions only)
---------------------------------------------------------
Update firmware to X.08.32(or higher) or X.21.00(or higher)
as applicable.
----------------------------------------------------------
HP-UX Systems running snmpd or OPENVIEW
----------------------------------------------------------
The following patches are available now:
PHSS_26137 s700_800 HP-UX 10.20 OV EMANATE14.2 Agent$
PHSS_26138 s700_800 HP-UX 11.X OV EMANATE14.2 Agent$

All three patches are available from:

**Revised 01**
- -->> In addition PHSS_26137 and PHSS_26138 are now available
from:
http://itrc.hp.com
============================================================
NOTE: The patches are labeled OV (Open View). However, the
patches are also applicable to systems that are _NOT_
running Open View.
============================================================
Workaround for HP-UX Systems:
If a patch is not available for your platform or you cannot
install an available patch, snmpd and snmpdm can be disabled
by removing their entries from /etc/services and removing the
execute permissions from /usr/sbin/snmpd and /usr/sbin/snmpdm.
