DESCRIPTION:
Some vulnerabilities have been reported in ISC BIND, which can be
exploited by malicious people to cause a DoS (Denial of Service).

1) Errors within the "Response Policy Zones" (RPZ) feature when
processing DNAME and CNAME records can be exploited to terminate the
named process.

Successful exploitation requires that recursion is enabled and the
server is configured to use RPZ.

2) A vulnerability is caused due to an error when handling UPDATE
requests.

For more information:
SA45082

SOLUTION:
Update to version 9.8.0-P4.
