A vulnerability in the BIND name server could allow a remote attacker to cause a denial of service against an affected system.
The Berkeley Internet Name Domain (BIND) is a popular Domain Name System (DNS) implementation from Internet Systems Consortium (ISC). A buffer overflow error exists in the handling of the q_usedns array used by the server to track nameservers and addresses that have been queried. This vulnerability only affects BIND versions 8.4.4 and 8.4.5.
A remote attacker may be able to cause the name server daemon to crash, thereby causing a denial of service for DNS operations.
