CVE-2009-0858: D.j.bernstein Djbdns

Medium severity, CVSS 5.8. EPSS: 6.3% chance of exploitation in the next 30 days.

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.
