whether a file exists.

What Is a Cisco Security Notice?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco 
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 
Security Notice.

Partners, authorized resellers, or service providers. For these products, 
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.
