K14601 : BIND vulnerability CVE-2012-5689

Security Advisory Description

ISC BIND 9.8.x through 9.8.4-P1 and 9.9.x through 9.9.2-P1, in certain configurations involving DNS64 with a Response Policy Zone that lacks an AAAA rewrite rule, allows remote attackers to cause a denial of service (assertion failure and named daemon exit) via a query for an AAAA record. (CVE-2012-5689)

BIG-IP configurations using DNS64 (the DNS IPv6 to IPv4 option configured in the DNS profile) and Response Policy Zone (RPZ) Rewriting together are affected by this CVE.

Note: RPZ Rewriting is an optional BIND 9.x configuration that allows administrators to create DNS deny lists.

Impact

Remote attackers may be able to cause a denial-of-service (DoS) attack by making a query for an AAAA record.
