ISC BIND 9 Denial of Service Vulnerability

Industry Reference:CVE-2009-0696.

ISC BIND 9 contains a vulnerability that may allow a remote attacker to create a denial-of-service condition. The Berkeley Internet Name Domain (BIND) is a popular Domain Name System (DNS) implementation from Internet Systems Consortium (ISC). It includes support for dynamic DNS updates. BIND 9 can crash when processing a specially-crafted dynamic update packet. By sending a specially-crafted dynamic update packet to a BIND 9 server, a remote, unauthenticated attacker can cause a denial of service by causing BIND to crash. This protection will detect and block DNS update requests for RR of type ANY.

Security Gateway R70: A new protection is now available.
VPN-1 NGX R65 & VSX NGX R65: A new protection is now available.
