Impact:
Modification of system information

Description:
A vulnerability was reported in BIND. 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.
The vendor indicates that the vulnerability exists in the DNS protocol itself, rather than in any particular vendor's implementation.
Systems using BIND as a caching resolver are affected.

Impact:
