ISC BIND 9 DNS64 Handling DoS

Description

The remote host is running Bind, a popular name server.

Versions of BIND earlier than 9.8.4-P1 / 9.9.2-P1 are potentially affected by a denial of service vulnerability. Affected versions of BIND can be forced to crash via malicously crafted DNS request.

Solution

Upgrade to BIND 9.8.4-P1 / 9.9.2-P1 or later. Alternatively, disable DNS64 functionality via configuration options.
