It was discovered that Bind incorrectly handled rewriting certain query responses when using both DNS64 and RPZ. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
