From $URL : 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.
