What Is a Cisco Security Notice?

Security Notices to inform customers of low- to mid-level severity security 
issues involving Cisco products.

Customers who wish to upgrade to a software version that includes fixes for 
these issues should contact their normal support channels. Free software 
updates will not be provided for issues that are disclosed through a Cisco

appropriate in the intended network before it is deployed.
