For Public Release 2012 March 28 16:00 UTC (GMT)
+--------------------------------------------------------------------
Summary
=======
A vulnerability in the Multicast Source Discovery Protocol (MSDP)
implementation of Cisco IOS Software and Cisco IOS XE Software could
allow a remote, unauthenticated attacker to cause a reload of an
affected device. Repeated attempts to exploit this vulnerability could
result in a sustained denial of service (DoS) condition.
Cisco has released free software updates that address this
vulnerability. Workarounds that mitigate this vulnerability are
available. This advisory is available at the following link:
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-msdp
Note: The March 28, 2012, Cisco IOS Software Security Advisory bundled
publication includes nine Cisco Security Advisories. Each advisory
lists the Cisco IOS Software releases that correct the vulnerability
or vulnerabilities detailed in the advisory as well as the Cisco IOS
Software releases that correct all vulnerabilities in the March 2012
bundled publication.
Individual publication links are in "Cisco Event Response: Semi-Annual
Cisco IOS Software Security Advisory Bundled Publication" at the

Affected Products
=================
Vulnerable Products
+------------------
The following products are affected by this vulnerability:
+ Cisco IOS Software
+ Cisco IOS XE Software
To determine whether a Cisco IOS or Cisco IOS XE Software release is
running on a Cisco product, administrators can log in to the device
and issue the "show version" command to display the system banner.
The system banner confirms that the device is running Cisco IOS
Software by displaying text similar to "Cisco Internetwork Operating
System Software" or "Cisco IOS Software." The image name displays in
parentheses, followed by "Version" and the Cisco IOS Software release
name. Other Cisco devices do not have the "show version" command or may
provide different output.
The following example identifies a Cisco product that is running
Cisco IOS Software Release 12.4(20)T with an installed image name of
C1841-ADVENTERPRISEK9-M:
Router#show version
Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3)

Cisco products are currently known to be affected by this vulnerability.
Details
=======
MSDP is the protocol used to connect multiple Protocol Independent
Multicast sparse mode (PIM-SM) domains. MSDP allows multicast sources
for a group to be known to all rendezvous points (RPs) in different
domains. An RP runs MSDP over TCP to discover multicast sources.
An RP in a PIM-SM domain has an MSDP peering relationship with
MSDP-enabled routers in another domain. The peering relationship occurs
over a TCP connection, where primarily a list of sources sending to
multicast groups is exchanged. The TCP connections between RPs are
achieved by the underlying routing system. The receiving RP uses the
source lists to establish a source path.
The purpose of this topology is to have domains discover multicast
sources in other domains. If the multicast sources are of interest to a
domain that has receivers, multicast data is delivered over the normal,
source-tree building mechanism in PIM-SM.
An MSDP packet containing encapsulated Internet Group Management
Protocol (IGMP) data, received from an external MSDP-configured peer
router, can cause an affected device to reload. This vulnerability can
only be exploited if the router is explicitly joined to the multicast
group. The MSDP packet destination address is a unicast address and
can be addressed to any IP address on the affected device, including
loopback addresses.
Transit traffic will not trigger this vulnerability.
A vulnerable interface configuration contains an explicitly joined
multicast group. Some example configurations that permit exploitation of
this vulnerability are:
!--- Interface configured for SAP Listener Support (a common
multicast group)
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
ip sap listen
!--- Interface configured to join a multicast group
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
ip igmp join-group 224.2.127.254
You can also use the "show igmp interface" command to determine if an
interface is joined to a multicast group.
RouterA#show ip igmp interface
GigabitEthernet0/0 is up, line protocol is up
Internet address is 192.168.0.1/24
IGMP is enabled on interface
Current IGMP host version is 2
Current IGMP router version is 2
IGMP query interval is 60 seconds
IGMP querier timeout is 120 seconds
IGMP max query response time is 10 seconds
Last member query count is 2
Last member query response interval is 1000 ms
Inbound IGMP access group is not set
IGMP activity: 2 joins, 0 leaves
Multicast routing is disabled on interface
Multicast TTL threshold is 0
Multicast groups joined by this system (number of users):
224.2.127.254(2) 239.255.255.255(1)
This vulnerability is documented in Cisco bug ID CSCtr28857. This
vulnerability has been assigned Common Vulnerabilities and Exposures
(CVE) ID CVE-2012-0382.
Vulnerability Scoring Details

(IKE) feature and are vulnerable to Cisco bug ID CSCts38429 when the
devices are running Layer 3 images; however, this product reached
the End of Software Maintenance milestone. Cisco 3550 Series SMI
Switches that are running Layer 2 images do not support IKE and are not
vulnerable. No other Cisco devices that run 12.2SE-based software are
vulnerable.

Cisco IOS XR Software
+--------------------
Cisco IOS XR Software is not affected by any of the vulnerabilities
disclosed in the March 2012 Cisco IOS Software Security Advisory
Bundled Publication.
Workarounds
===========
Customers with an MSDP-configured router who do not require membership
to multicast groups can remove the "ip sap listen" or "ip igmp
join-group <multicast-group address>" commands on the router interface
as a workaround.
For example:
RouterA#conf t
RouterA(config)# interface GigabitEthernet0/0
RouterA(config-if)# no ip sap listen
RouterA(config-if)# no ip igmp join-group 224.2.127.254
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
To determine if a router is configured for MSDP peers, run the
command "show ip msdp peer" at the router command prompt:
RouterA# show ip msdp peer
MSDP Peer 192.168.0.2 (?), AS 100
Connection status:
State: Up, Resets: 0, Connection source: none configured
Uptime(Downtime): 01:23:42, Messages sent/received: 25/24
Output messages discarded: 0
Connection and counters cleared 01:15:14 ago
SA Filtering:
Input (S,G) filter: none, route-map: none
Input RP filter: none, route-map: none
Output (S,G) filter: none, route-map: none
Output RP filter: none, route-map: none
SA-Requests:
Input filter: none
Peer ttl threshold: 0
SAs learned from this peer: 0
Input queue size: 0, Output queue size: 0
Message counters:
RPF Failure count: 0
SA Messages in/out: 13/8
SA Requests in: 0
SA Responses out: 0
Data Packets in/out: 7/8
To remove an untrusted MSDP peer from your configuration, use the "no
ip msdp peer <address>" or "ip msdp default-peer <ip-address | name>"
command on the router configuration interface.
RouterA(config)# no ip msdp peer 192.168.0.2
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
ip pim sparse-mode
Obtaining Fixed Software
========================
Cisco has released free software updates that address the
vulnerability|vulnerabilities described in this advisory. Prior to
deploying software, customers are advised to consult their
maintenance providers or check the software for feature set
compatibility and known issues that are specific to their
environments.
Customers may only install and expect support for feature
sets they have purchased. By installing, downloading,
accessing, or otherwise using such software upgrades, customers
agree to follow the terms of the Cisco software license at
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html,
or as set forth at
http://www.cisco.com/public/sw-center/sw-usingswc.shtml.
Do not contact psirt@cisco.com or security-alert@cisco.com for
software upgrades.
Customers with Service Contracts
+-------------------------------
Customers with contracts should obtain upgraded software through their
regular update channels. For most customers, upgrades should be obtained
through the Software Center on Cisco.com at http://www.cisco.com.
Customers Using Third-Party Support Organizations
+------------------------------------------------
Customers with Cisco products that are provided or maintained through
prior or existing agreements with third-party support organizations,
such as Cisco Partners, authorized resellers, or service providers,
should contact that organization for assistance with the appropriate
course of action.
The effectiveness of any workaround or fix depends on specific
customer situations, such as product mix, network topology, traffic
behavior, and organizational mission. Because of the variety of
affected products and releases, customers should consult their
service providers or support organizations to ensure that any applied
workaround or fix is the most appropriate in the intended network
before it is deployed.
Customers Without Service Contracts
+----------------------------------
Customers who purchase directly from Cisco but do not hold a Cisco
service contract and customers who make purchases through third-party
vendors but are unsuccessful in obtaining fixed software through
their point of sale should obtain upgrades by contacting the Cisco
Technical Assistance Center (TAC):
* +1 800 553 2447 (toll free from within North America)
* +1 408 526 7209 (toll call from anywhere in the world)
* e-mail: tac@cisco.com
Customers should have the product serial number available and be
prepared to provide the URL of this advisory as evidence of
entitlement to a free upgrade. Customers without service contracts
should request free upgrades through the TAC.
Refer to Cisco Worldwide Contacts at
http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html
for additional TAC contact information, including localized telephone
numbers, instructions, and e-mail addresses for support in various
languages.
