Severity: Medium
Published: Mar 9, 2009, 9:30:00 PM UTC
Source: [NVD] · [CVE record]
EPSS: 6.28% · Oct 25, 2026

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.
