      Affected Products
      =================
      
      Vulnerable Products
      +------------------
      
      Only Cisco 7200 Series and Cisco 7301 routers with VPN Acceleration
      Module 2+ (VAM2+) are affected by this vulnerability.
      
      To display a summary of the configuration information for the crypto
      engines and to determine if a VAM is present and used in the device,
      use the "show crypto engine brief" command, as shown in the following
      example:
      
          Router#show crypto engine brief
                  crypto engine name:  Virtual Private Network (VPN) Module
                  crypto engine type:  hardware
                               State:  Enabled 
                            Location:  slot 4
                  VPN Module in slot:  4
                        Product Name:  VAM2+ 
                   Software Serial #:  55AA
                           Device ID:  001F - revision 0000
                           Vendor ID:  0000
                         Revision No:  0x001F0000
                        VSK revision:  0
                        Boot version:  902
                         DPU version:  0
                         HSP version:  3.4(3) (PRODUCTION)
                        Time running:  00:00:10
                         Compression:  Yes
                                 DES:  Yes
                               3 DES:  Yes
                             AES CBC:  Yes (128,192,256)
                            AES CNTR:  No
               Maximum buffer length:  4096
                    Maximum DH index:  5120
                    Maximum SA index:  5120
                  Maximum Flow index:  10230
      
      Note: In the previous example, the "Product Name" VAM2+ is displayed,
      indicating that the router has the VAM2+ installed. The Enabled 
      keyword under "State" indicates that the VAM2+ is enabled and active.
      
      IKE is enabled by default if IPsec is used. Cisco IOS devices that
      are configured for IKE will listen on UDP port 500, UDP port 4500 if
      the device is configured for NAT Traversal (NAT-T), or UDP ports 848
      or 4848 if the device is configured for Group Domain of
      Interpretation (GDOI). The following outputs show a router that is
      listening on UDP port 500:
      
              Router#show ip sockets 
              Proto    Remote      Port      Local       Port  In Out Stat TTY OutputIF
              ....
               17   --listen--          192.168.66.129    500   0   0   11   0 
              ....
          
          Or
          
              Router#show udp
              Proto        Remote      Port      Local       Port  In Out  Stat TTY OutputIF
               17       --listen--          192.0.2.1         500   0   0  1011   0 
               17(v6)   --listen--          --any--           500   0   0 20011   0 
              Router#
      
      To determine the Cisco IOS Software release that 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 12.3(26) with an installed image name of
      C2500-IS-L:
      
          Router#show version
          Cisco Internetwork Operating System Software
          IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2)

      Details
      =======
      
      IPsec is an IP security feature that provides robust authentication
      and encryption of IP packets. IKE is a key management protocol
      standard that is used with the IPsec standard.
      
      IKE is a hybrid protocol that implements the Oakley and SKEME key
      exchanges inside the Internet Security Association and Key Management
      Protocol (ISAKMP) framework. (ISAKMP, Oakley, and SKEME are security
      protocols that are implemented by IKE.). More information on IKE is
      available at the following link:
      
      http://www.cisco.com/en/US/docs/ios/sec_secure_connectivity/configuration/guide/sec_key_exch_ipsec.html
      
      A vulnerability exists in the Cisco IOS Software implementation of
      IKE where a malformed packet may cause a device running Cisco IOS
      Software to reload. Only Cisco 7200 Series and Cisco 7301 routers
      running Cisco IOS software with a VPN Acceleration Module 2+ (VAM2+)
      installed are affected.
      
      This vulnerability is documented in Cisco Bug ID CSCtb13491 and has

      Workarounds
      ===========
      
      There are no workarounds available.
      
      Obtaining Fixed Software
      ========================
      
      Cisco has released free software updates that address this
      vulnerability. Prior to deploying software, customers should consult
      their maintenance provider or check the software for feature set
      compatibility and known issues specific to their environment.
      
      Customers may only install and expect support for the feature sets
      they have purchased. By installing, downloading, accessing or
      otherwise using such software upgrades, customers agree to be bound
      by the terms of Cisco's software license terms found at:
      
      http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html
      
      or as otherwise set forth at Cisco.com Downloads at:
      
      http://www.cisco.com/public/sw-center/sw-usingswc.shtml
      
      Do not contact psirt at cisco dot com or security-alert at cisco dot com for
      software upgrades.
      
      Customers with Service Contracts
      +-------------------------------
      
      Customers with contracts should obtain upgraded software through
      their regular update channels. For most customers, this means that
      upgrades should be obtained through the Software Center on Cisco's
      worldwide website at http://www.cisco.com.
      
      Customers using Third Party Support Organizations
      +------------------------------------------------
      
      Customers whose Cisco products 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 support organization for guidance and assistance
      with the appropriate course of action in regards to this advisory.
      
      The effectiveness of any workaround or fix is dependent on specific
      customer situations, such as product mix, network topology, traffic
      behavior, and organizational mission. Due to the variety of affected
      products and releases, customers should consult with their service
      provider or support organization to ensure any applied workaround or
      fix is the most appropriate for use in the intended network before it
      is deployed.
      
      Customers without Service Contracts
      +----------------------------------
      
      Customers who purchase direct from Cisco but do not hold a Cisco
      service contract, and customers who purchase through third-party
      vendors but are unsuccessful in obtaining fixed software through
      their point of sale should acquire upgrades by contacting the Cisco
      Technical Assistance Center (TAC). TAC contacts are as follows.
      
        * +1 800 553 2447 (toll free from within North America)
        * +1 408 526 7209 (toll call from anywhere in the world)
        * e-mail: tac at cisco dot com
      
      Customers should have their product serial number available and be
      prepared to give the URL of this notice as evidence of entitlement to
      a free upgrade. Free upgrades for non-contract customers must be
      requested through the TAC.
      
      Refer to:
      
      http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html
