Summary

A vulnerability in the implementation of the Remote Authentication Dial-in 
User Services (RADIUS) code of Cisco ASA Software could allow an 
authenticated, remote attacker to cause an affected system to reload.

The vulnerability is due to insufficient validation of RADIUS packets 
including crafted attributes. An attacker could exploit this vulnerability by
sending crafted RADIUS packets to the affected system. The attacker must know
the RADIUS shared secret and inject the crafted packet while a RADIUS exchange
is in progress.

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

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.
