DESCRIPTION:
Two vulnerabilities have been reported in BIND, which can be
exploited by malicious people to bypass certain restrictions or cause
a DoS (Denial of Service).

1) An error may allow access to the cache via recursion even though
an ACL disallows it.

Successful exploitation requires BIND running as both authoritative
and recursive DNS server in the same view.

2) An error when processing records from an authoritative server
during DNSSEC query validation can be exploited to cause a server to
crash via a bad signature in the response.

Successful exploitation requires BIND to be configured as a DNSSEC
validating server with multiple trust anchors configured for the same
zone.

The vulnerabilities are reported in version 9.7.2 through 9.7.2-P1.

SOLUTION:
Update to version 9.7.2-P2.

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits Alexandre Simon.
2) Reported by the vendor.
