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.

For additional information about Cisco PSIRT publications, see the Cisco 
Security Vulnerability Policy at 
http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

Customers Using Third-Party Support Organizations

Customers may have Cisco products that are provided or maintained through 
prior or existing agreements with third-party support organizations, such as 
Cisco 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.
