      Affected Products
      =================
      
      Vulnerable Products
      +------------------
      
      Devices that are running Cisco IOS Software and configured for PIM
      have a vulnerability related to a specially crafted PIM packet. In
      addition, Cisco 12000 Series (GSR) routers running Cisco IOS Software
      have a second vulnerability related to a crafted PIM packet.
      
      The show running-config | include ip pim command can be issued to
      verify that a Cisco IOS device is configured for PIM. In the
      following example, the Cisco IOS router is configured for PIM
      sparse-dense mode.
      
          Router#show running-config | include ip pim
           ip pim sparse-dense-mode
      
      Note that available PIM modes on a Cisco IOS device are dense mode,
      sparse mode, or sparse-dense mode. A device that is configured for
      any of these modes is affected by these vulnerabilities. The mode
      determines how the device populates its multicast routing table and
      how multicast packets are forwarded. PIM must be enabled in one of
      these modes for an interface to perform IP multicast routing. More
      information on the configuration of each mode is in the "Details"
      section.
      
      Additionally, To display information about interfaces configured for
      Protocol Independent Multicast (PIM), use the show ip pim interface
      command in user EXEC or privileged EXEC mode, as shown in the
      following example:
      
          Router# show ip pim interface
      
          Address          Interface                Ver/   Nbr    Query  DR     DR
                                                    Mode   Count  Intvl  Prior
      
          10.1.0.1         GigabitEthernet0/0       v2/SD  0      30     1      10.1.0.1
          10.6.0.1         GigabitEthernet0/1       v2/SD  1      30     1      10.6.0.2
      
      In order to determine the software that runs on a Cisco IOS product,
      log in to the device and issue the show version command to display
      the system banner. Cisco IOS software identifies itself as
      "Internetwork Operating System Software" or simply "IOS." On the next
      line of output, the image name displays between parentheses, followed
      by "Version" and the Cisco IOS release name. Other Cisco devices do
      not have the show version command or give different output.
      
      The following example shows output from a device that runs an IOS
      image:
      
          router>show version
          Cisco IOS Software, 7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(6)T2, RELEASE SOFTWARE (fc1)

      Products Confirmed Not Vulnerable
      +--------------------------------
      
      Cisco IOS devices that are not configured for PIM are not vulnerable.
      Cisco IOS XR Software is not affected by this vulnerability. No other
      Cisco products are currently known to be affected by this
      vulnerability.
      
      Details
      =======
      
      Two crafted Protocol Independent Multicast (PIM) packet
      vulnerabilities exist in Cisco IOS Software that may lead to a denial
      of service (DoS) condition. Devices that run Cisco IOS Software and
      are configured for PIM are affected by the first vulnerability. Only
      Cisco 12000 Series (GSR) routers that are configured for PIM are
      affected by the second vulnerability.
      
      Available PIM modes on a Cisco IOS device are dense mode, sparse
      mode, or sparse-dense mode. The mode determines how the device
      populates its multicast routing table and how multicast packets are
      forwarded. PIM must be enabled in one of these modes for an interface
      to perform IP multicast routing.
      
      Note: There is no default mode setting. By default, multicast routing
      is disabled on an interface.
      
      To configure PIM on an interface to be in dense mode, use the
      following command in interface configuration mode:
      
          Router(config-if)# ip pim dense-mode
      
      To configure PIM on an interface to be in sparse mode, use the
      following command in interface configuration mode:
      
          Router(config-if)# ip pim sparse-mode
      
      To configure PIM on an interface to be in sparse-dense mode, use the
      following command in interface configuration mode:
      
          Router(config-if)# ip pim sparse-dense-mode
      
      These vulnerabilities are documented in the following Cisco Bug IDs:
      
        * CSCsd95616 - Crafted PIM packets may cause an IOS device to
          reload
        * CSCsl34355 - GSR may crash with malformed PIM packets
      
      These vulnerabilities have been assigned the Common Vulnerabilities
      and Exposures (CVE) identifiers CVE-2008-3808 and CVE-2008-3809.
      
      Vulnerability Scoring Details
      =============================
      
      Cisco has provided scores for the vulnerabilities in this advisory
      based on the Common Vulnerability Scoring System (CVSS). The CVSS
      scoring in this Security Advisory is done in accordance with CVSS
      version 2.0.
      
      CVSS is a standards-based scoring method that conveys vulnerability
      severity and helps determine urgency and priority of response.
      
      Cisco has provided a base and temporal score. Customers can then
      compute environmental scores to assist in determining the impact of
      the vulnerability in individual networks.
      
      Cisco has provided an FAQ to answer additional questions regarding
      CVSS at

      Impact
      ======
      
      Successful exploitation may cause a reload of the affected device.
      Repeated exploitation could result in a sustained denial of service
      (DoS) condition.
      
      Software Versions and Fixes
      ===========================
      
      When considering software upgrades, also consult 
      http://www.cisco.com/go/psirt and any subsequent advisories to 
      determine exposure and a complete upgrade solution.
      
      In all cases, customers should exercise caution to be certain the
      devices to be upgraded contain sufficient memory and that current
      hardware and software configurations will continue to be supported
      properly by the new release. If the information is not clear, contact
      the Cisco Technical Assistance Center (TAC) or your contracted
      maintenance provider for assistance.
      
      Each row of the Cisco IOS software table (below) names a Cisco IOS
      release train. If a given release train is vulnerable, then the
      earliest possible releases that contain the fix (along with the
      anticipated date of availability for each, if applicable) are listed
      in the "First Fixed Release" column of the table. The "Recommended
      Release" column indicates the releases which have fixes for all the
      published vulnerabilities at the time of this Advisory. A device
      running a release in the given train that is earlier than the release
      in a specific column (less than the First Fixed Release) is known to
      be vulnerable. Cisco recommends upgrading to a release equal to or
      later than the release in the "Recommended Releases" column of the
      table.

      Workarounds
      ===========
      
      Specifying trusted PIM neighbors is a workaround for both
      vulnerabilities. A PIM router must receive PIM Hellos to establish
      PIM neighborship. PIM neighborship is also the basis for designated
      router (DR) election, DR failover, and accepting/sending PIM Join/
      Prune/Assert messages. To specify trusted PIM neighbors, use the ip
      pim neighbor-filter command, as shown in the following example:
      
          Router(config)#access-list 1 permit host 10.10.10.123
      
          !-- An access control list is created to allow a trusted PIM neighbor
          !-- in this example the neighbor is 10.10.10.123
          !
      
          Router(config)#interface fastEthernet 0/0
          Router(config-if)#ip pim neighbor-filter 1
      
          !-- The PIM neighbor filter is then applied to the respective interface(s)
      
      
      The ip pim neighbor-filter command filters PIM packets from untrusted
      devices including Hellos, Join/Prune, and BSR packets.
      
      Note: The vulnerabilities described in this document can be exploited
      by spoofed IP packets if the attacker knows the IP address of the
      trusted PIM neighbors listed in the ip pim neighbor-filter
      implementation.
      
      To protect infrastructure devices and minimize the risk, impact, and
      effectiveness of direct infrastructure attacks, administrators are
      advised to deploy ACLs to perform policy enforcement of traffic sent
      to core infrastructure equipment. PIM is IP protocol 103. As an
      additional workaround, administrators can explicitly permit only
      authorized PIM (IP protocol 103) traffic sent to infrastructure
      devices in accordance with existing security policies and
      configurations. An ACL can be deployed as shown in the following
      example:
      
          ip access-list extended Infrastructure-ACL-Policy
      
           !
           !-- When applicable, include explicit permit statements for trusted
           !-- sources that require access on the vulnerable protocol
           !-- PIM routers need to communicate with the rendezvous point (RP).
           !-- In this example, 192.168.100.1 is the IP address of the 
           !-- rendezvous point, which is a trusted host that requires access 
           !-- to and from the affected PIM devices.
           !
      
           permit pim host 192.168.100.1 192.168.60.0 0.0.0.255
           permit pim 192.168.60.0 0.0.0.255 host 192.168.100.1
      
           !
           !-- Permit PIM segment traffic, packets have destination of:
           !-- 224.0.0.13 (PIMv2)
           !-- 224.0.0.2  (Required only by legacy PIMv1)
           !
      
           permit pim 192.168.60.0 0.0.0.255 host 224.0.0.13
           permit pim 192.168.60.0 0.0.0.255 host 224.0.0.2
      
           !
           !-- The following vulnerability-specific access control entries
           !-- (ACEs) can aid in identification of attacks
           !
      
           deny pim any 192.168.60.0 0.0.0.255
      
           !
           !-- Explicit deny ACE for traffic sent to addresses configured within
           !-- the infrastructure address space
           !
      
           deny ip any 192.168.60.0 0.0.0.255
      
           !
           !-- Permit/deny all other Layer 3 and Layer 4 traffic in accordance
           !-- with existing security policies and configurations
           !
           !-- Apply iACL to interfaces in the ingress direction
           !
