ISC reports:

A very uncommon combination of zone data has been found that triggers a bug in BIND, with the result that named will exit with a "REQUIRE" failure in name.c when validating the data returned in answer to a recursive query.

A recursive resolver that is performing DNSSEC validation can be deliberately terminated by any attacker who can cause a query to be performed against a maliciously constructed zone. This will result in a denial of service to clients who rely on that resolver.
