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

The vulnerability is caused due to an error when remapping A records
into AAAA records while handling AAAA record lookups for an A record
rewrite rule in a Response Policy Zone (RPZ). This can be exploited
to trigger an assertion failure and terminate the named process.

Successful exploitation requires that both DNS64 and Response Policy
Zones are configured and that A rewrite rules are maintained but not
AAAA rewrite rules.

The vulnerability is reported in versions 9.8.0 through 9.8.4-P1 and
9.9.0 through 9.9.2-P1.

SOLUTION:
As a workaround ensure that the RPZ contains a AAAA rewrite rule for
every A rewrite rule. The vulnerability will be fixed in a beta
version scheduled to be released on January 24, 2013.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Pories Ediansyah, Institut Teknologi Bandung.
