Multiple Vulnerabilities in Cisco ASA Software

Cisco ASA Software is affected by the following vulnerabilities:

IKE Version 1 Denial of Service Vulnerability 
Crafted URL Denial of Service Vulnerability 
Denial of Service During Validation of Crafted Certificates 
DNS Inspection Denial of Service Vulnerability 

These vulnerabilities are independent of each other; a release that is affected by one of the vulnerabilities may not be affected by the others.

Successful exploitation of any of these vulnerabilities may result in a reload of an affected device, leading to a denial of service (DoS) condition.

Cisco has released software updates that address these vulnerabilities. Workarounds are available for some of these vulnerabilities.
