Description:
A vulnerability has been reported in BIND, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the validator within the "authvalidated()" function and may result in an internal consistency test failing when processing a specially crafted DNS datagram.
Successful exploitation causes named to exit, but requires that DNSSEC validation is enabled (not default setting).
The vulnerability affects BIND 9.3.0.
Solution:
Update to version 9.3.1.
