A vulnerability was discovered and corrected in bind :
BIND 9 nameservers using the DNS64 IPv6 transition mechanism are vulnerable to a software defect that allows a crafted query to crash the server with a REQUIRE assertion failure. Remote exploitation of this defect can be achieved without extensive effort, resulting in a denial-of-service (DoS) vector against affected servers (CVE-2012-5688).
The updated packages have been upgraded to bind 9.8.4-P1 which is not vulnerable to this issue.
