Description:
A vulnerability was reported in Sidewinder. A remote user can spoof the system.
The domain name system (DNS) service does not use sufficiently random UDP sockets to process queries. A remote user can send specially crafted DNS queries and responses to the target service to spoof responses and insert records into the DNS cache. This may cause traffic to be redirected to arbitrary IP addresses specified by the remote user.
Secure Computing CyberGuard is also affected.
Dan Kaminsky of IOActive reported this vulnerability.
