New! Plugin Severity Now Using CVSS v3

The DNS server running on the remote host is affected by a denial of service vulnerability.


According to its self-reported version number, the MaraDNS server running on the remote host is affected by a hash collision issue when large amounts of specially crafted queries with the Recursion Desired (RD) bit set are sent to the remote server. This issue could allow a remote attacker to crash the DNS server, resulting in a denial of service.


Upgrade to MaraDNS version / 1.4.10 or later.
