                                    Routers
                                       
Revision 1.0

Summary

   Three vulnerabilities have been discovered in Cisco SN 5420 Storage
   Router software releases up to and including 1.1(5). Two of the
   vulnerabilities can cause a Denial-of-Service attack. The other allows
   an access to the SN 5420 configuration if it has been previously saved
   on the router.
   
   There is no workaround for these vulnerabilities.
   
   No other Cisco product is vulnerable.
   
   This advisory is available at the

   such as Cisco Partners, authorized resellers, or service providers
   should contact that support organization for assistance with the
   upgrade, which should be free of charge.

   service contract and customers who purchase through third party
   vendors but are unsuccessful at obtaining fixed software through their
   point of sale should get their upgrades by contacting the Cisco
   Technical Assistance Center (TAC). TAC contacts are as follows:
