The response_addname function in response.c in Daniel J. Bernstein djbdns 1.05 and earlier does not constrain offsets in the required manner, which allows remote attackers, with control over a third-party subdomain served by tinydns and axfrdns, to trigger DNS responses containing arbitrary records via crafted zone data for this subdomain.
