ISC BIND 9 Remote Dynamic Update Message Denial of Service Vulnerability

ISC BIND 9 Remote Dynamic Update Message Denial of Service Vulnerability

ISC BIND is prone to a remote denial-of-service vulnerability because the software fails to properly handle specially crafted dynamic update requests.

Successfully exploiting this issue allows remote attackers to crash affected DNS servers, denying further service to legitimate users. Other attacks are also possible.

Versions prior to BIND 9.4.3-P3, 9.5.1-P3, and 9.6.1-P3 are vulnerable.
